The McDonnell FH Phantom is a twinjet fighter aircraft designed and first flown during World War II for the United States Navy. The Phantom was the first purely jet-powered aircraft to land on an American aircraft carrier and the first jet deployed by the United States Marine Corps. Although only 62 FH-1s were built it helped prove the viability of carrier-based jet fighters. As McDonnell's first successful fighter, it led to the development of the follow-on F2H Banshee, which was one of the two most important naval jet fighters of the Korean War; combined, the two established McDonnell as an important supplier of navy aircraft.
The McDonnell XF-88 Voodoo was a long-range, twinjet fighter aircraft with swept wings designed for the United States Air Force. Although it never entered production, its design was adapted for the subsequent supersonic F-101 Voodoo.
The Sikorsky CH-37 Mojave is an American large heavy-lift helicopter of the 1950s.
The Fairey Rotodyne was a 1950s British compound gyroplane designed and built by Fairey Aviation and intended for commercial and military uses. A development of the earlier Fairey Jet Gyrodyne, which had established a world helicopter speed record, the Rotodyne featured a tip-jet-powered rotor that burned a mixture of fuel and compressed air bled from two wing-mounted Napier Eland turboprops. The rotor was driven for vertical takeoffs, landings and hovering, as well as low-speed translational flight, but autorotated during cruise flight with all engine power applied to two propellers.
The Douglas A2D Skyshark was an American turboprop-powered attack aircraft built by the Douglas Aircraft Company for the United States Navy. The program was substantially delayed by engine reliability problems, and was canceled because more promising jet attack aircraft had entered development and the smaller escort carriers the A2D was intended to utilize were being phased out.
The Hiller YH-32 Hornet was an American ultralight helicopter built by Hiller Aircraft in the early 1950s. It was a small and unique design because it was powered by two Hiller 8RJ2B ramjet engines mounted on the rotor blade tips which weigh 13 lb (5.9 kg) each and deliver an equivalent of 45 hp (34 kW) for a total of 90 hp (67 kW). Versions of the HJ-1 Hornet were built for the United States Army and the United States Navy in the early 1950s.
The Focke-Wulf Triebflügel, or Triebflügeljäger, literally meaning "thrust-wing hunter", was a German concept for an aircraft designed in 1944, during the final phase of World War II, as a defence against the ever-increasing Allied bombing raids on central Germany. It was a vertical take-off and landing tailsitter interceptor design for local defense of important factories or areas which had small or no airfields.
The Fairey Jet Gyrodyne is a British experimental compound gyroplane built by the Fairey Aviation Company that incorporated helicopter, gyrodyne and autogyro characteristics. The Jet Gyrodyne was the subject of a Ministry of Supply (MoS) research contract to gather data for the follow-up design, the Rotodyne.
The Ling-Temco-Vought (LTV) XC-142 is a tri-service tiltwing experimental aircraft designed to investigate the operational suitability of vertical/short takeoff and landing (V/STOL) transports. An XC-142A first flew conventionally on 29 September 1964, and completed its first transitional flight on 11 January 1965 by taking off vertically, changing to forward flight, and finally landing vertically. Its service sponsors pulled out of the program one by one, and it eventually ended due to a lack of interest after demonstrating its capabilities successfully.
The Lockheed XH-51 was an American single-engine experimental helicopter designed by Lockheed Aircraft, utilizing a rigid rotor and retractable skid landing gear. The XH-51 was selected as the test vehicle for a joint research program conducted by the United States Army and United States Navy to explore rigid rotor technology.
The Sikorsky S-69 is an American experimental co-axial compound helicopter developed by Sikorsky Aircraft as the demonstrator of the Advancing Blade Concept (ABC) under United States Army and NASA funding.
The Fairey FB-1 Gyrodyne is an experimental British rotorcraft that used single lifting rotor and a tractor propeller mounted on the tip of the starboard stub wing to provide both propulsion and anti-torque reaction.
The NHI H-3 Kolibrie was a small helicopter developed in the Netherlands in the 1950s by Nederlandse Helikopter Industrie. It first flew in May 1956.
The McDonnell XV-1 is an experimental Convertiplane developed by McDonnell Aircraft for a joint research program between the United States Air Force and the United States Army to explore technologies to develop an aircraft that could take off and land like a helicopter but fly at faster airspeeds, similar to a conventional airplane. The XV-1 would reach a speed of 200 mph, faster than any previous rotorcraft, but the program was terminated due to the tip-jet noise and complexity of the technology which gave only a modest gain in performance.
The Kamov Ka-118 is a projected light multirole helicopter with the NOTAR configuration based on the McDonnell Douglas design.
The SNCASE SE.3200 Frelon (Hornet) is a French helicopter built in the late 1950s. Intended to serve as a multirole helicopter for the French Army, Air Forces and Navy, two prototypes were built and flown before the project was dropped in favour of the SA 3210 Super Frelon.
The Baumgärtl PB-64 was a 1950s single-seat helicopter designed and built by the Austrian-designer Paul Baumgärtl for the Brazilian Air Ministry. The PB-64 had an unusual rotor drive with two lightweight pulse jets mounted on the rotor, although not on the tips of the blades which was more normal. The engines were mounted at each end of a bar, at right-angles to the main rotor which also acted as a stabilizer bar. The main structure was a simple keel with a tricycle landing gear and an open seat for the pilot and a rudder on a simple tail boom.
The Curtiss-Bleecker Helicopter was an American prototype rotary wing aircraft, introduced in 1926. The thrust of the aircraft was distributed from a central mounted engine through shafts to propellers mounted on each rotor blade.
The McDonnell XHCH was a 1950s aerial crane helicopter proposal for the United States Navy by the McDonnell Corporation.
The McDonnell 120 Flying Crane, also V-1 Jeep, was a lightweight utility flying crane helicopter designed and built by the McDonnell Aircraft Corporation during the 1950s. The open frame fuselage supported the three gas-producers and main rotor mast, with a small single-seat cockpit in the nose, which was originally open, but later enclosed.
