The development of the helicopter was long. The program started in 1984, but the first prototype Ka-60-01 flew in December 1998, and the second in 2007. [6] A civil version, the Ka-62, was initially proposed when the Ka-60 programme was launched, but no production followed owing to development problems with the Ka-60's Saturn RD-600V 1500 hp ...
The Molniya (now Vympel) R-60 (NATO reporting name: AA-8 "Aphid") is a short-range lightweight infrared homing air-to-air missile designed for use by Soviet fighter aircraft. It has been widely exported , and remains in service with the CIS and many other nations.
The Aerostar emerged as a mid-wing cantilever monoplane powered by two wing-mounted piston engines, with retractable landing gear in a tricycle configuration. It is designed to seat six, and is distinguished from light twins of similar size and weight by its high wing loading, careful attention to fine aerodynamic details, a mid wing, and in early models, the absence of cowl flaps; Smith was ...
Although the official record for fastest piston-engined aeroplane in level flight was held by a Grumman F8F Bearcat, the Rare Bear, with a speed of 850.23 km/h (528.31 mph), the unofficial record for fastest piston-engined aeroplane in level flight is held by a British Hawker Sea Fury at 880 km/h (547 mph).
All Lightning variants had the excess thrust to slightly exceed 700 knots (1,300 km/h; 810 mph) indicated airspeed under certain conditions, [62] [89] [97] [page needed] and the service limit of 650 knots (1,200 km/h; 750 mph) was occasionally ignored. With the strengthened shock cone, the Lightning could safely approach its thrust limit, but ...
1783-12-01: 2.7 km (8,900 ft); Jacques Alexandre Charles and his assistant Marie-Noël Robert, both of France, made the first flight in a hydrogen balloon to about 610 m (2,000 ft). Charles then ascended alone to the record altitude. 1784-06-23: 4 km (13,000 ft); Pilâtre de Rozier and the chemist Joseph Proust in a Montgolfier.
The Sikorsky H-60 is a family of military helicopters built by Sikorsky Aircraft. All models use a modified mission symbol in addition to the 'H' vehicle type designator under the 1962 United States Tri-Service aircraft designation system (meaning, there is no aircraft named an "H-60" per se). The mission prefix (e.g. U, M, V) only has ...
The Sikorsky S-60 helicopter, a prototype "flying crane", was derived from the S-56 in 1958. Proving to be underpowered, the development of the S-60 led to the larger, turbine-engined Sikorsky CH-54 Tarhe military transport helicopter, and its civil S-64 Skycrane variant, which were already on the drawing board by the time the sole example of the S-60 crashed on 3 April 1961.
