NASA's Glenn Research Center's world-class facilities and expert staff help develop and verify cutting-edge technologies in the areas of aeronautics, aerospace and space. Our premier ground test facilities support powered flight through the atmosphere and beyond.

On this page:

We’ve developed supersonic aircraft, walked on the Moon, created a reusable space shuttle and an orbiting laboratory, and now we’re developing a spacecraft to take us to Mars. None of these mission accomplishments would have been possible without stringent and realistic testing. In this presentation from our 2017 Evening with the Stars event, NASA Glenn engineer Mary Lobo explains how we accurately simulate some of the harshest conditions found in the air and space to enable technology breakthroughs.Credits: NASA

Special Projects Laboratory

The Special Projects Laboratory (SPL) at NASA GRC played an important role in the center’s aeropropulsion research for over 70 years. The facility, named the Jet Propulsion Static Laboratory (JPSL) from 1944 to 1961, made notable contributions to the center’s propulsion and materials research before being removed in 2018. This website seeks to collect and preserve its history for future research.

NASA Glenn’s Arrival in Cleveland

In 1940, the NACA sought a location for its new engine research laboratory (today NASA Glenn Research Center). Cleveland, Ohio’s aviation industry and renowned airport made it a leading contender for the site, but it was the steadfast effort of a small cadre of local officials that secured the agreement. The endeavor has generated over 75 years of technical and economic impact for Cleveland. 

On this page:

Overview
The NASA Glenn Research Center is an essential component of the Cleveland community, but if not for the work of determined local officials in 1940, the laboratory could have easily ended up in Chicago or Dayton. Today, Glenn’s nearly 3,300 employees resolve a variety of technological and scientific issues for both industry and the Government. The center, however, began in 1941 as an engine research laboratory for the National Advisory Committee for Aeronautics (NACA).
As the United States participation in World War II became imminent, the NACA sought to construct two new research laboratories. Localities across the nation, including Cleveland, Ohio, vied to have the facilities situated in their region. The NACA devised an objective method to evaluate the bids. Cleveland and a Chicago location ranked the highest of the 72 submissions. When NACA officials reconfigured their ranking criteria, Cleveland gained a slight lead. The local power company then agreed to discount its electricity rates, and the deal was secured. The NACA announced the decision on November 25, 1940. A groundbreaking ceremony took place on January 23, 1941.

Return to Jet Engines

	Electrical Engineer Fred Looft (left) and Engineering Services Chief Robert Godman inspect a Pratt & Whitney TF30 turbofan engine at PSL. (10/6/1967)

	

In the late 1960s and 1970s, PSL undertook a series of engine studies for civilian and military aircraft. NASA also created two larger PSL test chambers to support the increased aeronautics work.
Overview
After nearly a decade of concentrating on rockets, the Lewis Research Center began returning to aircraft propulsion in 1966. During the interim, the jet engine took over the airline industry, and manufacturers were developing the next generation of the jet engine: the turbofan. The jumbo jet generation of airliners that emerged in the early 1970s was almost entirely powered by turbofan engines. Much of the work at PSL during the mid-1970s concentrated on making turbofan engines quieter and more efficient.
NASA Lewis instituted an Airbreathing Engine Division that used the Propulsion Systems Laboratory (PSL) No. 1 and 2 and other facilities to study the turbofans. The center also added two new test chambers with greater capabilities to the PSL complex. Unlike Lewis’ previous research, the majority of the new engine studies were for civilian aircraft and not the military.

Engine Calibration Study
In the late 1960s and early 1970s the center’s Airbreathing Engine Division sought to improve aircraft engine performance and fuel efficiency while reducing noise and emissions. In order to test the effect of experimentally modified engine components, NASA engineers first had to be able to determine the engine’s baseline performance characteristics.

Boundary Layer Ingestion Propulsion

The aviation industry has made tremendous strides in increasing the efficiency of today’s aircraft, especially by significantly reducing the fuel consumption of the aircraft engines. NASA's Glenn Research Center is working on propulsion technology to increase the fuel efficiency of future aircraft even more, reducing the overall cost to consumers and the impact on the environment.

The aviation industry has made tremendous strides in increasing the efficiency of today’s aircraft, especially by significantly reducing the fuel consumption of the aircraft engines. NASA’s Glenn Research Center is working on propulsion technology to increase the fuel efficiency of future aircraft even more, reducing the overall cost to consumers and the impact on the environment.
Overview
The “double bubble” D8 Series is one aircraft design concept that uses boundary layer ingestion. Credits: NASA/MIT/Aurora Flight Sciences
One of the ways to improve aircraft efficiency is to reduce the drag on the aircraft using the aircraft’s own engines. Engineers at NASA’s Glenn Research Center in Cleveland are testing a new kind of propulsion system using a principle called Boundary Layer Ingestion. Analytical studies have shown that this new technology has the potential to reduce the aircraft fuel burn by as much as 8.5% compared to aircraft flown today.
On today’s jet aircraft, the engines are typically located away from the aircraft’s body to avoid ingesting the layer of slower flowing air that develops along the aircraft’s surfaces, called the boundary layer. The new propulsor design, meaning the inlet and the fan, is embedded in the aircraft body at the back of the fuselage and ingests the slower boundary layer air flow, using it to generate the thrust needed to propel the aircraft through its mission.

Guide to Rockets

How are rockets made? The Beginner's Guide to Rockets will introduce you to the basics behind rocket science.

On this page:

The Beginner’s Guide to Rockets will help you learn the basic math and physics that govern the design and flight of rockets. We’ll look at many different kinds of rockets, from stomp rockets, which are a special kind of artillery shell, to bottle rockets, to model rockets, to full scale boosters. We’ll look at the similarities and the differences in these rockets and include some instructions for making and flying your own rockets. 
Here you can study how rockets operate at your own pace and to your own level of interest. The flight of the rocket involves the interaction of forces, so we include background pages on the fundamentals of forces. Aerodynamics plays a major role in the flight of toy rockets and in the generation of thrust for full scale rockets, so there are background pages devoted to basic aerodynamics. There are also background pages on thermodynamics and gas dynamics because of the role they play in rocket propulsion. Since we will be sending rockets to the Moon and Mars, we provide some background information on these destinations in addition to our home planet.
