The HAL Tejas Mark 2 (lit. "Radiance"), or Medium Weight Fighter (MWF), [2] is an Indian single-engine, canard delta wing, multirole combat aircraft designed by the Aeronautical Development Agency (ADA) in collaboration with Aircraft Research and Design Centre (ARDC) [3] of Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF).
Powered aircraft range is limited by the aviation fuel energy storage capacity (chemical or electrical) considering both weight and volume limits. [1] Unpowered aircraft range depends on factors such as cross-country speed and environmental conditions. The range can be seen as the cross-country ground speed multiplied by the maximum time in the ...
The Aero Commander 500 family is a series of light-twin piston-engined and turboprop aircraft originally built by the Aero Design and Engineering Company in the late 1940s, renamed the Aero Commander company in 1950, and later a division of Rockwell International in 1965.
The shaped edges smooth the mixing of hot air from the engine core and cooler air flowing through the engine fan, which reduces noise-creating turbulence. [37] Chevrons were developed by GE under a NASA contract. [31] Some notable examples of such designs are Boeing 787 and Boeing 747-8 – on the Rolls-Royce Trent 1000 and General Electric ...
The air flowing into a turbojet engine is always subsonic, regardless of the speed of the aircraft itself. The intake has to supply air to the engine with an acceptably small variation in pressure (known as distortion) and having lost as little energy as possible on the way (known as pressure recovery).

[2] [3] By July 2020, it had evolved into the 70–100 passenger range [4] In October 2020, Embraer released conceptual depictions of the 75–90 seat airliner, with a fuselage similar to the E-Jet and turboprops above a low wing but a different T-tail design.
Schematic diagram showing the operation of a turboprop engine Propulsive efficiency for different engine types and Mach numbers. Exhaust thrust in a turboprop is sacrificed in favor of shaft power, which is obtained by extracting additional power (beyond that necessary to drive the compressor) from turbine expansion.
