These lifting bodies were designed to validate the concept of flying a wingless vehicle back to Earth from space and landing it like an aircraft at a pre-determined site.<\/p>\n\n\n\n<p>These unique research vehicles, with their unconventional aerodynamic shapes, were the M2-F1, M2-F2, M2-F3, HL-10, X-24A, and the X-24B. The information the lifting body program generated contributed to the database that led to development of the space shuttle program.<\/p>\n\n\n\n<p>Aerodynamic lift \u2013 essential to flight in the atmosphere \u2013 was obtained from the shape of the vehicles rather than from wings as on a normal aircraft. The addition of fins and control surfaces allowed the pilots to stabilize and control the vehicles and regulate their flight paths.<\/p>\n\n\n\n<p>All but the M2-F1 were powered by the same type of XLR-11 rocket engine used in the Bell X-1 \u2013 the first aircraft to fly faster than the speed of sound. The M2-F1, a lightweight prototype, was unpowered.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><b>Background<\/b><\/h2>\n\n\n\n<p>The original idea of lifting bodies was conceived about 1957 by Dr. Alfred J.

H. Julian Allen, another Ames engineer, determined that a blunt nose cone was a desirable shape to survive the aerodynamic heating associated with re-entry from space. Eggers found that by slightly modifying a symmetrical nose cone shape, aerodynamic lift could be produced. This lift would enable the modified shape to fly back from space rather than plunge to earth in a ballistic trajectory.<\/p>\n\n\n\n<p>These studies by Eggers, Allen, and their associates led to the design known as the M-2, a modified half-cone, rounded on the bottom and flat on top, with a blunt, rounded nose and twin tail-fins. This configuration and those of the later lifting bodies allowed them to be maneuvered both in a lateral and a longitudinal direction so they could be landed on a runway rather than simply parachuting into the ocean as did the contemporary ballistic capsules used in the Mercury, Gemini, and Apollo programs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><b>The Pioneering M2-F1<\/b><\/h2>\n\n\n\n<p>In 1962, Flight Research Center Director Paul Bikle approved a program to build a lightweight, unpowered lifting body as a prototype to flight test the wingless concept. It would look like a \u201cflying bathtub,\u201d and was designated the M2-F1. Built by sailplane designer Gus Briegleb, it featured a plywood shell placed over a tubular steel frame crafted at the center. Construction was completed in 1963.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/www.nasa.gov\/image-article\/c-47-tows-m2-f1-lifting-body\/\"><img loading=\"lazy\" decoding=\"async\" width=\"1041\" height=\"1165\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328506main_E-10962_full-1.jpg?w=1041\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"C-47 Tows M2-F1 Lifting Body\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328506main_E-10962_full-1.jpg 1041w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328506main_E-10962_full-1.jpg?resize=268,300 268w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328506main_E-10962_full-1.jpg?resize=768,859 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328506main_E-10962_full-1.jpg?resize=915,1024 915w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328506main_E-10962_full-1.jpg?resize=357,400 357w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328506main_E-10962_full-1.jpg?resize=536,600 536w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328506main_E-10962_full-1.jpg?resize=804,900 804w\" sizes=\"(max-width: 1041px) 100vw, 1041px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">The M2-F1 lifting body is seen here being towed behind a C-47 at what is now NASA’s Armstrong Flight Research Center in Edwards, California.<\/div><div class=\"hds-credits\">NASA<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>The first flight tests saw the M2-F1 towed aloft by a hopped-up Pontiac convertible driven at speeds up to 120 mph across Rogers Dry Lake. These initial tests produced enough flight data about the M2-F1 to proceed with flights behind a NASA R4D tow plane at greater altitudes. The R4D (the Navy designation of the C-47 or civil DC-3) towed the craft to an altitude of 12,000 feet where it was released to fly freely back to Rogers Dry Lake. NASA research pilot Milt Thompson flew the M2-F1 during the first series of tests.<\/p>\n\n\n\n<p>Typical glide flights with the M2-F1 lasted several minutes at speeds of 110 to 120 mph.<\/p>\n\n\n\n<p>More than 400 ground tows and 77 aircraft tow flights were carried out with the M2-F1 before it was retired. A historical artifact now owned by the Smithsonian\u2019s National Air and Space Museum, the M2-F1 is on long-term loan to NASA Armstrong and has been restored to flight-like condition.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><b>The Heavyweights<\/b><\/h2>\n\n\n\n<p>The success of the M2-F1 program led to NASA\u2019s development and construction of two heavyweight lifting bodies based on studies at NASA\u2019s Ames and Langley research centers \u2013 the M2-F2 and the HL-10, both built by Northrop Corporation. The \u201cM\u201d refers to \u201cmanned\u201d and \u201cF\u201d refers to \u201cflight.\u201d \u201cHL\u201d comes from \u201chorizontal landing\u201d and \u201c10\u201d is for the 10th lifting body design that was investigated by Langley.<\/p>\n\n\n\n<p>The U.S. Air Force later became interested in lifting body research and had a third design concept, the X-24A, built by the Martin Company. It was later modified into the X-24B and both configurations were flown in the joint NASA\/Air Force lifting body program at the Flight Research Center.<\/p>\n\n\n\n<p>The basic flight profile of the heavyweight lifting bodies involved being air-launched by NASA\u2019s modified NB-52B \u201cmothership\u201d at an altitude of about 45,000 feet. The XLR-11 rocket engine was then ignited and the vehicle accelerated to speeds of up to 1,100 mph and to altitudes of 60,000 to 70,000 feet. After the rocket engine was shut down, the pilots began steep glides toward the Edwards runway. As the pilots entered the final approach leg, they increased their rate of descent to build up speed and used this energy to perform a \u201cflare out\u201d maneuver and slow their landing speed to about 200 mph \u2013 the same basic approach pattern and landing speed of today\u2019s space shuttles.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><b>M2-F2<\/b><\/h2>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/www.nasa.gov\/image-article\/f-104-flies-chase-m2-f2-research-flight\/\"><img loading=\"lazy\" decoding=\"async\" width=\"1041\" height=\"832\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328746main_EC66-1567_full.jpg?w=1041\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"F-104 Flies Chase for M2-F2 Research Flight\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328746main_EC66-1567_full.jpg 1041w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328746main_EC66-1567_full.jpg?resize=300,240 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328746main_EC66-1567_full.jpg?resize=768,614 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328746main_EC66-1567_full.jpg?resize=1024,818 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328746main_EC66-1567_full.jpg?resize=400,320 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328746main_EC66-1567_full.jpg?resize=600,480 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/328746main_EC66-1567_full.jpg?resize=900,719 900w\" sizes=\"(max-width: 1041px) 100vw, 1041px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">The M2-F2 lifting body returns from a research flight at what is now NASA’s Armstrong Flight Research Center in Edwards, California, with an F-104 flying chase.<\/div><div class=\"hds-credits\">NASA<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>The first flight of the M2-F2, which looked much like the M2-F1, occurred on July 12, 1966, with Thompson again at the controls.

Its glide-flight weight was 6,473 pounds and its maximum gross weight was more than 10,000 pounds.<\/p>\n\n\n\n<p>Flights of the HL-10 contributed substantially to the decision to design the space shuttles without air-breathing engines that would have been used for powered landings. The HL-10 flew its final flight on July 17, 1970, and the craft is now is now on public display at the entrance to NASA Armstrong.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/www.nasa.gov\/image-article\/x-24a-lifting-body-lakebed\/\"><img loading=\"lazy\" decoding=\"async\" width=\"1041\" height=\"816\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343986main_ECN-2006_full-1.jpg?w=1041\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"X-24\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343986main_ECN-2006_full-1.jpg 1041w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343986main_ECN-2006_full-1.jpg?resize=300,235 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343986main_ECN-2006_full-1.jpg?resize=768,602 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343986main_ECN-2006_full-1.jpg?resize=1024,803 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343986main_ECN-2006_full-1.jpg?resize=400,314 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343986main_ECN-2006_full-1.jpg?resize=600,470 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343986main_ECN-2006_full-1.jpg?resize=900,705 900w\" sizes=\"(max-width: 1041px) 100vw, 1041px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">This 1968 photo shows the bulbous X-24A lifting body research vehicle on the lakebed adjacent to what is now NASA’s Armstrong Flight Research Center in Edwards, California.<\/div><div class=\"hds-credits\">NASA<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<h2 class=\"wp-block-heading\"><b>X-24A<\/b> <\/h2>\n\n\n\n<p>Built for the Air Force by Martin, the X-24A was a bulbous-shaped aircraft, with three vertical fins at the rear for directional control. It weighed 6,270 pounds without propellants, was just more than 24 feet long, and had a width of nearly 14 feet. The first unpowered glide flight of the X-24A occurred on April 17, 1969, flown by Air Force Maj. Jerauld Gentry. Gentry also piloted the vehicle on its first powered flight on March 19, 1970.<\/p>\n\n\n\n<p>The X-24A was flown 28 times in a program that, like that of the HL-10, helped validate the concept that a wingless vehicle could be landed unpowered. Some three decades later, X-38 program managers elected to use the X-24A design to save money, since the existing X-24A aerodynamic database was complete. This limited the number of wind tunnel tests that would have been required for a totally new design.<\/p>\n\n\n\n<p>Fastest speed recorded by the the X-24A was 1,036 mph (Mach 1.6), and the maximum altitude reached by the craft was 71,400 feet. Both of those flights were flown by NASA research pilot John Manke, who was also the pilot on its final flight on June 4, 1971.<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-fit \"><a href=\"https:\/\/www.nasa.gov\/image-article\/x-24b-over-lakebed\/\"><img loading=\"lazy\" decoding=\"async\" width=\"1041\" height=\"816\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343837main_EC75-4643_full-1.jpg?w=1041\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"X-24B over the Lakebed\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343837main_EC75-4643_full-1.jpg 1041w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343837main_EC75-4643_full-1.jpg?resize=300,235 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343837main_EC75-4643_full-1.jpg?resize=768,602 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343837main_EC75-4643_full-1.jpg?resize=1024,803 1024w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343837main_EC75-4643_full-1.jpg?resize=400,314 400w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343837main_EC75-4643_full-1.jpg?resize=600,470 600w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/03\/343837main_EC75-4643_full-1.jpg?resize=900,705 900w\" sizes=\"(max-width: 1041px) 100vw, 1041px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">The X-24B lifting body is seen here in flight over the lakebed at what is now NASA’s Armstrong Flight Research Center in Edwards, California.<\/div><div class=\"hds-credits\">NASA<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<h2 class=\"wp-block-heading\"><b>X-24B<\/b><\/h2>\n\n\n\n<p>The X-24B\u2019s design evolved from a family of potential re-entry shapes proposed by the Air Force Flight Dynamics Laboratory, each with higher lift-to-drag ratios.<\/p>\n\n\n\n<p>To reduce the costs of constructing a research vehicle, the Air Force returned the X-24A to Martin for modifications that converted its bulbous shape into one resembling a \u201cflying flatiron\u201d \u2013 a rounded top, flat bottom, and a double-delta planform that ended in a pointed nose.<\/p>\n\n\n\n<p>Manke was first to fly the X-24B, a glide flight on Aug. 1, 1973. He was also the pilot on the first powered mission on Nov. 15, 1973.<\/p>\n\n\n\n<p>Among the final flights with the X-24B were two precise landings on the main concrete runway at Edwards, which showed that accurate unpowered re-entry vehicle landings were operationally feasible. These missions, flown by Manke and Air Force Maj. Mike Love, represented the final milestone in a program that helped write the flight plan for today\u2019s space shuttle landings.<\/p>\n\n\n\n<p>The final powered flight with the X-24B was on Sept. 23, l975, flown by Bill Dana. It was also the last rocket-powered lifting body flight flown at the Flight Research Center. Ironically, it was Dana who also flew the last X-15 rocket plane mission about seven years earlier.<\/p>\n\n\n\n<p>Top speed reached by the X-24B was 1,164 mph (Mach 1.75) by Love on Oct. 25, 1974. The highest altitude reached was 74,100 feet by Manke on May 22, 1975.<\/p>\n\n\n\n<p>The X-24B is now on public display at the Air Force Museum at Wright-Patterson Air Force Base,Ohio.<\/p>\n\n\n<div id=\"\" class=\"hds-topic-cards nasa-gb-align-full maxw-full width-full padding-y-6 padding-x-3 color-mode-dark hds-module hds-module-full wp-block-nasa-blocks-topic-cards\">\t\t<div class=\"grid-container grid-container-block-lg padding-x-0\">\n\t\t\t<div class=\"grid-row flex-align-center margin-bottom-3\">\n\t\t\t\t<div class=\"desktop:grid-col-8 margin-bottom-2 desktop:margin-bottom-0\">\n\t\t\t\t\t<div class=\"label color-carbon-60 margin-bottom-2\">Keep Exploring<\/div>\n\t\t\t\t\t<h2 class=\"heading-36 line-height-sm\">Discover More About Armstrong<\/h2>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t<div class=\"grid-row grid-gap-2 hds-topic-cards-wrapper\">\n\t\t\t\t\t<a href=\"https:\/\/www.nasa.gov\/armstrong\/capabilities-facilities\/\" class=\"mobile:grid-col-12 tablet:grid-col-6 desktop:grid-col-3 topic-card margin-bottom-4 desktop:margin-bottom-0\">\n\t\t\t\t<div class=\"hds-topic-card hds-cover-wrapper cover-hover-zoom bg-carbon-black\">\n\t\t\t\t\t<div class=\"skrim-overlay skrim-overlay-dark skrim-left mobile-skrim-top padding-3 display-flex flex-align-end flex-justify-start z-200\">\n\t\t\t\t\t\t<div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<p class=\"hds-topic-card-heading heading-29 color-spacesuit-white line-height-sm margin-top-0 margin-bottom-1\">\n\t\t\t\t\t\t\t\t<span>Armstrong Capabilities & Facilities<\/span>\n\t\t\t\t\t\t\t\t<svg viewBox=\"0 0 32 32\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><circle class=\"color-nasa-red\" cx=\"16\" cy=\"16\" r=\"16\"><\/circle><path d=\"M8 16.956h12.604l-3.844 4.106 1.252 1.338L24 16l-5.988-6.4-1.252 1.338 3.844 4.106H8v1.912z\" class=\"color-spacesuit-white\"><\/path><\/svg>\n\t\t\t\t\t\t\t<\/p>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<figure class=\"hds-media-background  \"><img loading=\"lazy\" decoding=\"async\" width=\"1920\" height=\"1279\" src=\"https:\/\/images-assets.nasa.gov\/image\/AFRC2022-0063-096\/AFRC2022-0063-096~large.jpg?w=1920&h=1279&fit=clip&crop=faces%2Cfocalpoint\" class=\"attachment-1536x1536 size-1536x1536\" alt=\"\" style=\"transform: scale(1);
