What Is The Best Jet Engine?
The Early PioneersFrank Whittle was the first to register a patent for the turbojet engine in 1930.Hans Von Ohain was granted a patent for his turbojet in 1936.However, Hans Von Ohain was the first to fly in 1939 with the Heinkel He-178.Frank Whittles jet, the Gloster E.28/39 first flew in 1941.
What Are The Different Types Of Jet Engines?
The Different Types Of Jet Engine Are:• Gas Turbine• Turbojet • Ramjet• Turbofan• Turboprop
• Propfan• Turboshaft• Scramjet• Pulsejet• Rocket
• Turborocket
Propulsive Performance Of Different Jet Engines
Propulsive Efficiency At 100mph:Turbo Prop:40%High By Pass Turbojet:30%Low By Pass Turbojet:30%Pure Turojet:15%
At 400mph:Turbo Prop:80%High By Pass Turbojet:70%Low By Pass Turbojet:65%Pure Turojet:45%
Pure Turbojets have much higher efficiency at high speeds, about 1000mph and above.Turboprops are very effective at lower speeds, under 400mph.Vertical/Short take-off and landing engines (VSTOL) such as the Rolls Royce Pegasus, can be used to take off from very short distance runways, or even just strait up!
