Is turbojet engine same as ramjet engine?
In a ramjet, the high pressure is produced by “ramming” external air into the combustor using the forward speed of the vehicle. The external air that is brought into the propulsion system becomes the working fluid, much like a turbojet engine. Therefore, ramjets are lighter and simpler than a turbojet.
How much fuel does a ramjet use?
In a typical engine, 100 pounds of air/sec. is combined with only 2 pounds of fuel/sec. Most of the hot exhaust has come from the surrounding air. Flame holders in the burner localize the combustion process. Burning occurs subsonically in the ramjet and supersonically in the scramjet.
What fuel do ramjets use?
Unlike its main speed competition, the rocket, which burns fuel using onboard oxidizers like ammonium nitrate, potassium chlorate or ammonium chlorate, ramjets breathe air. Thus, while rockets can operate in the near vacuum of space, ramjets must fly through the atmosphere.
How does a ramjet take off?
Most ramjets operate at supersonic flight speeds and use one or more conical (or oblique) shock waves, terminated by a strong normal shock, to slow down the airflow to a subsonic velocity at the exit of the intake. Further diffusion is then required to get the air velocity down to a suitable level for the combustor.
What are the specs for a RamJet 350 engine?

What kind of engine does a Chevy ramjet 502 have?
The RAMJET 502 engine is based on the marine electronic, port fuel injection system, and the Chevrolet Performance 502/502 crate engine. The RAMJET 502 engine includes an aluminum intake manifold, fully calibrated Engine Control Module (ECM), wiring harness, all the necessary sensors, distributor, ignition coil, throttle body, fuel
How is the acceleration of a ramjet achieved?
For a ramjet operating at a subsonic-flight Mach number, exhaust flow is accelerated through a converging nozzle. For a supersonic-flight Mach number, acceleration is typically achieved by a convergent–divergent nozzle. One of the two Bristol Thor ramjet engines on a Bristol Bloodhound missile
When was the first ramjet engine used in an airplane?
That August, he developed the first ramjet engine for use as an auxiliary motor of an aircraft, the DM-1. The world’s first ramjet-powered airplane flight took place in December 1940, using two DM-2 engines on a modified Polikarpov I-15.
