Spitfire Mark I. 

The Spitfire Mark I was a utility helicopter built in the United States in the late 1970s and intended for series production. In essence, the Mark I was an Enstrom F-28 that was modified to use an Allison 250 turboshaft engine and geared transmission in place of the original piston engine and system of vee belts. The resulting powerplant installation was lighter and more compact, which allowed for additional cargo or fuel.

Spitfire Helicopters' parent company, Fetsko Aviation Sales and Transportation began work on the prototype in January 1976, and on a number of pre-production aircraft in February 1977. Fetsko displayed a mockup of the concept at the National Maintenance and Operations Meeting at Reading, Pennsylvania in June 1976.

The prototype (registered N4890) first flew in December 1978. By May 1979, Spitfire had supplemental approval for the turbine conversion and by July, the company reported that it had sold 42 examples of the Mark I and Mark II and expected to build 60 aircraft during 1980. The engine installation on production models was to be slightly further forward than on the prototype.

However, Spitfire remained dependent on Enstrom to supply airframes for remanufacture, and Enstrom distanced itself from the project somewhat. Competing plans by Enstrom and Spitfire to market Polish-built Mil Mi-2 helicopters in the United States might have contributed to the friction. In Spitfire's version of the deal, Polish manufacturer PZL-Świdnik would also contribute to the Spitfire manufacturing efforts. By November 1979, Enstrom refused to supply airframes to Spitfire.

The situation improved somewhat in the 1980s, and Spitfire president Jack Fetsko reported in May 1983 that relations with Enstrom had improved to the point where the two companies could "talk programs". By that time, costs had increased from $US 165,000 expected in 1979 to $US 285,000 but Spitfire had taken deposits for 50 Mark Is, and had a firm sale for the first production aircraft. Together with companies Sodian and Soprea, Spitfire formed a new venture, Spitfire Helicopters International, to manufacture the Mark I and Mark II in Málaga, Spain.

Nothing came of the joint venture, and Spitfire's attempts to market F-28 derivatives came to an end. In the 1990s, Enstrom marketed its own turbine-powered version of the F-28 as the Enstrom 480.

2011 Garbuzovo Antonov An-148 crash. On 5 March 2011, an Antonov An-148 passenger jet broke up in mid-air and crashed on the outskirts of Garbuzovo, a village in the Belgorod Oblast of Russia. All six crew members, the only people on board, were killed. The aircraft was on a demonstration flight prior to delivery to the Myanmar Air Force. The subsequent investigation concluded that the aircraft broke up after the crew allowed it to substantially exceed its maximum design speed during a practice emergency descent.

Accident
The An-148 was on a local demonstration flight from Pridacha Airport in Voronezh, Russia, where it had been built by aircraft manufacturer VASO. The aircraft was being readied for delivery to the Myanmar Air Force, two representatives of which were on board. The other four crew, all Russians, were two pilots and two engineers.

At 10:40 Moscow time, the aircraft crashed at Garbuzovo, a small village in the Alexeevsky Region of the Belgorod Oblast, some  south of Moscow, narrowly missing some houses.

The wreckage was found strewn along a  track, after witnesses on the ground reported seeing parts of the airframe breaking off before impact. None of the six people on board survived.

Aircraft
The aircraft involved was a twinjet Antonov An-148-100E, c/n 41-03, carrying test registration 61708. It was operating its 32nd flight, in preparation for delivery to the Myanmar air force. Just days before the accident, the type had been granted extended certification.

Investigation
The Russian Ministry of Industry opened an investigation into the accident. A criminal investigation was launched by the Investigative Committee of Russia to decide whether violation of flight regulations occurred. The flight recorders were recovered, and the whole wreckage was transported to the VASO plant for examination.

The investigation was completed in April 2011, and concluded that the crew inadvertently permitted the aircraft to accelerate over  above its maximum design speed, or never exceed speed (VNE), during an emergency descent. The abnormal aerodynamic stress exceeded the strength of the airframe, inducing low-frequency oscillations that eventually resulted in structural failure and in-flight break-up. Contributing factors were lack of proper crew coordination in executing the emergency descent, deviations from recommended procedures and the misleading indications provided by basic flight instruments while outside normal operating conditions.

Mauro Solar Riser. The Mauro Solar Riser is an American biplane ultralight electric aircraft that was the first crewed aircraft to fly on solar power. It was also only the second solar-powered aircraft to fly, after the uncrewed AstroFlight Sunrise, which had first flown  years earlier.

Design and development
The president of Ultralight Flying Machines, Larry Mauro, created the Solar Riser by converting a stock UFM Easy Riser hang glider to solar power. Normally foot-launched, the Solar Riser had wheeled landing gear added. Power is supplied by a Bosch electric starter motor of  connected to a 30-volt DC Nickel-cadmium battery pack taken from a Hughes 500 helicopter, powering a  propeller through a reduction drive made from a timing belt and two pulleys. The battery was charged by a series of photovoltaic solar panels mounted in the top wing that provided 350 watts of power. The solar cells were not sufficient to provide all power in flight, so all flights were made by recharging the battery on the ground from the solar cells and then flying using energy stored in the battery. A charge in bright sunshine for an hour and a half yielded a flight of 3–5 minutes.

Because the battery power was enough to launch the aircraft for a soaring flight it was theoretically possible to launch on battery power, soar while the batteries are being charged by sunlight and then continue powered flight. The Solar Riser did not employ the most efficient cells available at the time, and the upper wing had room for twice the number of cells to be installed. Early plans called for upgrading and increasing the number of cells so that sustained electric flight could be made using only solar energy and not battery power, but these plans were never completed.

Operational history
With Larry Mauro as the pilot, the Solar Riser made the first man-carrying flight on solar power at noon on 29 April 1979 at Flabob Airport at Rubidoux, California, near Riverside. The aircraft reached a maximum height of about  and flew . A number of other flights of similar height and duration were flown, including demonstration flights at EAA AirVenture Oshkosh before the aircraft was retired to a museum.

Sodium aluminium phosphate. Sodium aluminium phosphate (SAlP) describes the inorganic compounds consisting of sodium salts of aluminium phosphates.  The most common SAlP has the formulas NaH14Al3(PO4)8·4H2O and Na3H15Al2(PO4)8. These materials are prepared by combining alumina, phosphoric acid, and sodium hydroxide.

In addition to the usual hydrate, an anhydrous SAlP is also known, Na3H15Al2(PO4)8
(CAS#10279-59-1), referred to as 8:2:3, reflecting the ratio of phosphate to aluminium to sodium.  Additionally an SAlP of ill-defined stoichiometry is used (NaxAly(PO4)z (CAS# 7785-88-8).

The acidic sodium aluminium phosphates are used as acids for baking powders for the chemical leavening of baked goods. Upon heating, SAlP combines with the baking soda to give carbon dioxide.  Most of its action occurs at baking temperatures, rather than when the dough or batter is mixed at room temperature.  SAlPs are advantageous because they impart a neutral flavor.  

As a food additive, it has the E number E541.  Basic sodium aluminium phosphates are also known, e.g., Na15Al3(PO4)8.  These species are useful in cheese making.

UFM Easy Riser. The UFM Easy Riser is an American swept wing biplane hang glider that was first powered in 1975, becoming the first modern ultralight aircraft. The Easy Riser was still in production as an unpowered glider in 2002 by Ultralight Flying Machines.

Design and development
The Easy Riser was developed by Larry Mauro from the earlier Kiceniuk Icarus II biplane hang glider. An engine was installed by John Moody in 1975 so the glider could be launched from flat terrain.

Early powered versions consisted simply of a motor added to the foot-launched hang glider version with control by a combination of weight shift for pitch and tip rudders for roll and yaw, with the tip rudders used together as air brakes. Because many pilots could not run fast enough to achieve take-off, wheeled tricycle gear was added. The aircraft exhibited poor pitch stability, so a horizontal stabilizer and elevator were added. Finally, on later versions, the tip rudders were replaced with a tail-mounted rudder.

The Easy Riser is constructed with an aluminium structure and stamped ribs, covered in doped aircraft fabric covering, Mylar or other coverings. The pilot sits on a fabric sling seat. Engines used include the  McCulloch MAC-101,  Hirth F-36 and Solo 210.

Easy Risers were produced in large numbers until the ultralight market downturn of the early 1980s when the type was taken out of production. Later, the unpowered glider version was put back into limited production.

In 1979, Larry Mauro installed solar cells and an electric motor on a stock Easy Riser and the resulting Mauro Solar Riser become the first solar powered aircraft to carry a person aloft.

Maareech ATDS. Maareech Advanced Torpedo Decoy System (ATDS) is a torpedo detection and countermeasure system used by the Indian Navy. The system offers a complete solution to detect and locate an incoming torpedo and to apply countermeasures to protect naval platform against torpedo attack. It was developed as a joint project of the Naval Physical and Oceanographic Laboratory (NPOL), Kochi and the Naval Science and Technological Laboratory (NSTL), Visakhapatnam.

Description 
It is an anti-torpedo system with towed and expendable decoys. The system is capable of detecting, confusing, diverting and decoying the incoming torpedoes. The decoy helps in exhausting the energy of the torpedo by running the latter through long and ineffective course and prevents them from homing in to the targeted platform with its advanced countermeasures capabilities.

Mareech systems is being deployed on all current and future frontline warships of Indian Navy ships.

The underwater arrays for Maareech are being manufactured by KELTRON Controls at Aroor while the system is being integrated by Bharat Electronics Limited (BEL).

Norfolk and Suffolk Aviation Museum. The Norfolk and Suffolk Aviation Museum is a museum collection of aircraft and aviation-related artefacts, located near the former RAF Bungay airfield in Flixton in the north of the English county of Suffolk.

Details

First established in 1972 as the Norfolk and Suffolk Aviation Society, the museum houses a varied array of over 60 complete or partial aircraft, including rarities such as the only complete de Havilland Sea Vixen FAW.1 in private ownership, a flyable replica of the Colditz Cock escape glider, a Vickers Valetta VX580 C.2 and an FMA IA 58 Pucará that was captured by British forces during the Falklands War.

In addition to the aircraft displayed, the museum also houses thematic collections devoted to subjects including the Royal Observer Corps, RAF Bomber Command, RAF Air-Sea Rescue and RAF Coastal Command.

As well as preserving its existing collections, the museum and its members are actively involved in the exploration and study of aircraft crash sites – termed wreckology – in East Anglia. The museum charges no entrance fee and is entirely funded by public donations, corporate sponsorship, and local and European government grants. It employs only one full-time member of staff, with day-to-day maintenance and running of the museum falling largely on the shoulders of a team of volunteers.

Eminent autogyro exponent Wing Commander Ken Wallis had a long association with the museum, dating from shortly after its opening. For many years his Wallis WA-116 Agile autogyro, Little Nellie, made famous by its appearance in the 1967 James Bond film You Only Live Twice, was on display at Flixton. Wallis served as the museum's president until his death in September 2013.
