The ducts also proved to have higher losses than expected, and a series of modifications were not able to solve this problem to any large degree. These problems reduced maximum lift at higher altitudes out of the ground effect to 3,150 lb (1,430 kg), less than the empty weight of the aircraft at 4,285 lb (1,944 kg).
The Block 1 version of the ship (used through November 2024) produces a total of 12.25 MN (2,750,000 lb f) [62] almost triple the thrust of the Saturn V second stage, with this total being expected to increase to 15.69 MN (3,530,000 lb f) for Block 2 boosters and later up to 26.48 MN (5,950,000 lb f) with the Block 3 vehicle.
The upgraded M-46, weighing 8.4 tonnes, has a range of 39 km. [22] The warhead per round has been increased from 3.4 kg of TNT to 8 kg of TNT. After the upgrade the total length and width of the gun measured 11.84 m and 2.45 m with a 6.9 m-long barrel.
Kawasaki engineers used a stacked design for a liquid-cooled, 998 cc (60.9 cu in) inline four-cylinder engine. The crankshaft axis, input shaft, and output shaft of the Ninja ZX-10R engine are positioned in a triangular layout to reduce engine length, while the high-speed generator is placed behind the cylinder bank to reduce engine width.
Type 56-1 – Copy of the AKS, with an under-folding steel shoulder stock and the bayonet removed to make the weapon easier to carry. As with the original Type 56, milled receivers were replaced by stamped receivers in the mid-1960s, making the Type 56-1 an equivalent to the Russian AKMS .
The rake is 25°, trail is 98 mm (3.9 in), wheelbase is 1,460 mm (57 in), and seat height is 800 mm (31 in). It has a tested dry weight (minus fuel only) of 206 kg (455 lb) and a tested wet weight of 220 kg (485 lb). [21] The chain drive is a 530 chain with stock gearing of 16 tooth front and 43 tooth rear sprockets.
The Air Force expected to use the Space Shuttle to launch large satellites, and required it to be capable of lifting 29,000 kg (65,000 lb) to an eastward LEO or 18,000 kg (40,000 lb) into a polar orbit. The satellite designs also required that the Space Shuttle have a 4.6 by 18 m (15 by 60 ft) payload bay.
The request for proposals issued on 6 January 1972 called for a 20,000-pound (9,100 kg) class air-to-air day fighter with a good turn rate, acceleration, and range, and optimized for combat at speeds of Mach 0.6–1.6 and altitudes of 30,000–40,000 feet (9,100–12,000 m). This was the region where USAF studies predicted most future air ...
