The transonic speed range is that range of speeds within which the airflow over different parts of an aircraft is between subsonic and supersonic. So the regime of flight from Mcrit up to Mach 1.3 is called the transonic range. Supersonic: 1.2–5.0 794–3,308 915–3,806 1,470–6,126 410–1,702
3.78 cm – amount of distance the Moon moves away from Earth each year [114] 4.3 cm – minimum diameter of a golf ball [115] 5 cm – usual diameter of a chicken egg; 5 cm – height of a hummingbird, the smallest-known bird; 5.08 cm – 2 inches, 5.5 × 5.5 × 5.5 cm – dimensions of a 3x3x3 Rubik's cube; 6.1 cm – average height of an apple
The Mikoyan MiG-29 (Russian: Микоян МиГ-29; NATO reporting name: Fulcrum) is a twin-engine fighter aircraft designed in the Soviet Union.Developed by the Mikoyan design bureau as an air superiority fighter during the 1970s, the MiG-29, along with the larger Sukhoi Su-27, was developed to counter U.S. fighters such as the McDonnell Douglas F-15 Eagle and the General Dynamics F-16 ...
[62] [67] [69] It is made up of titanium plates with thicknesses varying from 0.5 to 1.5 inches (13 to 38 mm) determined by a study of likely trajectories and deflection angles. The armor makes up almost six percent of the A-10's empty weight.
The MiG-21 jet fighter was a continuation of Soviet jet fighters, starting with the subsonic MiG-15 and MiG-17, and the supersonic MiG-19.A number of experimental Mach 2 Soviet designs were based on nose intakes with either swept-back wings, such as the Sukhoi Su-7, or tailed deltas, of which the MiG-21 would be the most successful.
Up to four young, or kits, are born in spring and summer, after a three or four-month gestation. [31] [94] Newborn beavers are precocial with a full fur coat, and can open their eyes within days of birth. [24] [31] Their mother is the primary caretaker, while their father maintains the territory. [9] Older siblings from a previous litter also ...
Hydrochloric acid is produced in solutions up to 38% HCl (concentrated grade). Higher concentrations up to just over 40% are chemically possible, but the evaporation rate is then so high that storage and handling require extra precautions, such as pressurization and cooling. Bulk industrial-grade is therefore 30% to 35%, optimized to balance ...
Design work on Messerschmitt Project Number P.1034 began in March 1934, just three weeks after the development contract was awarded. The basic mock-up was completed by May, and a more detailed design mock-up was ready by January 1935. The RLM designated the design as type "Bf 109", the next available from a block of numbers assigned to BFW. [8]
