  2. Mach number - Wikipedia

    en.wikipedia.org/wiki/Mach_number

    At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). An F/A-18 Hornet creating a vapor cone at transonic speed just before reaching the speed of sound. The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas.

  3. Sukhoi Su-35 - Wikipedia

    The Sukhoi Su-35 Super Flanker (Russian: Сухой Су-35; NATO reporting name: Flanker-E/M) is the designation for two improved derivatives of the Su-27 air-defence fighter.

  4. FIM-92 Stinger - Wikipedia

    en.wikipedia.org/wiki/FIM-92_Stinger

    The FIM-92 Stinger is an American man-portable air-defense system (MANPADS) that operates as an infrared homing surface-to-air missile (SAM). It can be adapted to fire from a wide variety of ground vehicles, and from helicopters and drones as the Air-to-Air Stinger (ATAS).

  5. Tumansky R-25 - Wikipedia

    en.wikipedia.org/wiki/Tumansky_R-25

    The Tumansky R-25 was designed as a replacement for the Tumansky R-13 in MiG-21 fighters. The R-25 is a two-spool axial-flow turbojet with a new compressor with increased overall pressure ratio and airflow, variable two-stage afterburner, and greater use of titanium.

  6. Fuel economy in aircraft - Wikipedia

    en.wikipedia.org/wiki/Fuel_economy_in_aircraft

    For supersonic flight, drag increases at Mach 1.0 but decreases again after the transition. With a specifically designed aircraft, such as the (discontinued) Aerion AS2 , the Mach 1.1 range at 3,700 nmi is 70% of the maximum range of 5,300 nmi at Mach 0.95, but increases to 4,750 nmi at Mach 1.4 for 90% before falling again.

  7. DF-41 - Wikipedia

    en.wikipedia.org/wiki/DF-41

    The Dongfeng-41 or DF-41 (simplified Chinese: 东风-41; traditional Chinese: 東風-41; lit. 'East Wind-41'; NATO reporting name: CH-SS-20 [4]; previously reported as CSS-10 [5]) is a fourth-generation Chinese solid-fuelled road-mobile intercontinental ballistic missile operated by the People's Liberation Army Rocket Force (formerly the Second Artillery Corps).

  8. Talwar-class frigate - Wikipedia

    en.wikipedia.org/wiki/Talwar-class_frigate

    It is a three-stage missile in which the terminal stage reaches supersonic velocity (Mach 2.9) when it is approximately 20 km (12 mi) from its target. [ 35 ] The later batches of 7 ships ( Teg onwards) are fitted with the BrahMos supersonic cruise missile, which has a range of 300 kilometres (190 mi) and moves with the velocity of Mach 3 ...

  9. Steady flight - Wikipedia

    en.wikipedia.org/wiki/Steady_flight

    Forces acting on an airplane in steady level longitudinal flight, also known as straight and level flight, with a very small angle of attack. In steady level longitudinal flight, thrust counterbalances drag and lift supports the aircraft's weight.
