The McDonnell Douglas F-15 Eagle is an American twin-engine, all-weather tactical fighter aircraft designed by McDonnell Douglas. Following reviews of proposals, the United States Air Force (USAF) selected McDonnell Douglas's design in 1969 to meet the service's need for a dedicated air superiority fighter. The Eagle first flew in July 1972, and entered service in 1976. It is among the most successful modern fighters, with over 100 victories and no losses in aerial combat, with the majority of the kills by the Israeli Air Force.
The Douglas B-18 Bolo is an American heavy bomber which served with the United States Army Air Corps and the Royal Canadian Air Force during the late 1930s and early 1940s. The Bolo was developed by the Douglas Aircraft Company from their DC-2, to replace the Martin B-10.
The McDonnell XF-85 Goblin is an American prototype fighter aircraft conceived during World War II by McDonnell Aircraft. It was intended to deploy from the bomb bay of the giant Convair B-36 bomber as a parasite fighter. The XF-85's intended role was to defend bombers from hostile interceptor aircraft, a need demonstrated during World War II. McDonnell built two prototypes before the Air Force (USAAF) terminated the program.
The Cessna A-37 Dragonfly, or Super Tweet, is an American light attack aircraft developed from the T-37 Tweet basic trainer in the 1960s and 1970s by Cessna of Wichita, Kansas. The A-37 was introduced during the Vietnam War and remained in peacetime service afterward.
The Douglas DC-6 is a piston-powered airliner and cargo aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, Douglas reworked it after the war to compete with the Lockheed Constellation in the long-range commercial transport market. Douglas built over 700, and many still fly in cargo, military, and wildfire control roles.
The Lockheed/Boeing/General Dynamics YF-22 is an American single-seat, twin-engine fighter aircraft technology demonstrator designed for the United States Air Force (USAF). The design was a finalist in the USAF's Advanced Tactical Fighter competition, and two prototypes were built for the demonstration/validation phase of the competition. The YF-22 won the contest against the Northrop YF-23, and entered production as the Lockheed Martin F-22 Raptor. The YF-22 has a similar aerodynamic layout and configuration as the F-22, but with differences in the position and design of the cockpit, tail fins and wings, and in internal structural layout.
The North American F-107 is North American Aviation's entry in a United States Air Force tactical fighter-bomber design competition of the 1950s. The F-107 was based on the F-100 Super Sabre, but included many innovations and radical design features, notably the over-fuselage air intakes. The competition was eventually won by the Republic F-105 Thunderchief, and two of the three F-107 prototypes ended their lives as test aircraft. One is on display at the National Museum of the United States Air Force and a second at Pima Air and Space Museum.
The Lockheed JetStar is a business jet produced from the early 1960s to the 1970s. The JetStar was the first dedicated business jet to enter service, as well as the only such airplane built by Lockheed. It was also one of the largest aircraft in the class for many years, seating ten plus two crew. It is distinguishable from other small jets by its four engines, mounted on the rear of the fuselage, and the "slipper"-style fuel tanks fixed to the wings.
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 Kaman HH-43 Huskie is a helicopter with intermeshing rotors used by the United States Air Force, the United States Navy and the United States Marine Corps from the 1950s until the 1970s. It was primarily used for aircraft firefighting and rescue in the close vicinity of air bases, but was later used as a short-range overland search and rescue aircraft during the Vietnam War.
The Sikorsky R-4 is a two-seat helicopter that was designed by Igor Sikorsky with a single, three-bladed main rotor and powered by a radial engine. The R-4 was the world's first large-scale mass-produced helicopter and the first helicopter used by the United States Army Air Forces, the United States Navy, the United States Coast Guard and the United Kingdom's Royal Air Force and Royal Navy. In U.S. Navy and U.S. Coast Guard service, the helicopter was known as the Sikorsky HNS-1. In British service it was known as the Hoverfly.
The Republic XF-84H "Thunderscreech" was an American experimental turboprop aircraft derived from the F-84F Thunderstreak. Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the program's cancellation.
The Ling-Temco-Vought (LTV) XC-142 was 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 on 11 January 1965, it completed its first transitional flight 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 Stinson L-1 Vigilant is an American liaison aircraft designed by the Stinson Aircraft Company of Wayne, Michigan and manufactured at the Vultee-Stinson factory in Nashville, Tennessee. The aircraft was operated by the United States Army Air Corps as the O-49 until 1942.
The Consolidated PT-1 Trusty was a biplane primary trainer used by the United States Army Air Service (USAAS).
The Sikorsky S-61R is a twin-engine helicopter used in transport or search and rescue roles. A developed version of the S-61/SH-3 Sea King, the S-61R was also built under license by Agusta as the AS-61R. The S-61R served in the United States Air Force as the CH-3C/E Sea King and the HH-3E Jolly Green Giant, and with the United States Coast Guard as the HH-3F "Pelican".
The Tupolev ANT-25 was a Soviet long-range experimental aircraft which was also tried as a bomber. First constructed in 1933, it was used by the Soviet Union for a number of record-breaking flights.
A number of aircraft have been claimed to be the fastest propeller-driven aircraft. This article presents the current record holders for several sub-classes of propeller-driven aircraft that hold recognized, documented speed records in level flight. Fédération Aéronautique Internationale (FAI) records are the basis for this article. Other contenders and their claims are discussed, but only those made under controlled conditions and measured by outside observers. Pilots during World War II sometimes claimed to have reached supersonic speeds in propeller-driven fighters during emergency dives, but these speeds are not included as accepted records. Neither are speeds recorded in a dive during high-speed tests with the Supermarine Spitfire, including Squadron Leader J.R. Tobin's 606 mph (975 km/h) in a 45° dive in a Mark XI Spitfire and Squadron Leader Anthony F. Martindale's breaking 620 mph (1,000 km/h) in the same aircraft in April 1944. Flight Lieutenant Edward Powles' 690 mph (1,110 km/h) in Spitfire PR.XIX PS852 during an emergency dive while carrying out spying flights over China on 5 February 1952 is also discounted. This would otherwise be the highest speed ever recorded for a piston-engined aircraft.
Edson Fessenden Gallaudet was a pioneer in the field of aviation. He was best known for his development of practical airfoils and aircraft propulsion systems for use in early seaplanes.
The Gallaudet DB-1B was a United States daytime bomber designed during World War I. It was the successor to the Gallaudet DB-1, a very heavy aircraft with flight control issues and serious structural problems with the wings, which never got past the ground test phase. The DB-1B was lighter than the DB-1, having redesigned, stronger wings. The DB-1B, unlike its predecessor, did manage to complete several test flights. However, the project was scrapped when flight performance was poor.
