The turboramjet can be run in turbojet mode at takeoff and during low-speed flight but then switch to ramjet mode to accelerate to high Mach numbers. The turbojet core is mounted inside a duct that contains a combustion chamber downstream of the turbojet nozzle. The turboramjet is a hybrid engine that essentially consists of a turbojet mounted inside a ramjet. The air turboramjet engine is a combined cycle engine that merges aspects of turbojet and ramjet engines. Recreated schematic of an air turboramjet, featuring 1. Cooling the engine is not a problem because the burner and its hot exhaust gases are located behind the turbine blades. It is not a true rocket, so it cannot operate in space. The turborocket design offers a mixture of benefits with drawbacks. This allows operation at a much higher altitude than a normal engine would allow. The idea behind a turborocket is to supplement the atmospheric oxygen with an onboard supply.

Once a jet engine goes high enough in an atmosphere, there is insufficient oxygen to burn the jet fuel. The turbine exhaust gases mix with the fan discharge air, and combust with the air from the compressor before exhausting through a convergent-divergent propelling nozzle. It typically comprises a multi-stage fan driven by a turbine, which is driven by the hot gases exhausting from a series of small rocket-like motors mounted around the turbine inlet.

The air turborocket fills a niche (in terms of cost, reliability, ruggedness, and duration of thrust) between the solid-fuel rocket motor and gas turbine engine for missile applications.Ī turborocket is a type of aircraft engine combining elements of a jet engine and a rocket.

In addition, it provides thrust throughout a much wider speed range than a ramjet, yet is much cheaper and easier to control than a gas turbine engine. For the same carried mass of propellant as a rocket motor, the overall output of the air turborocket is much higher. The benefit of this setup is increased specific impulse over that of a rocket. 2.3 Conditions for usage of turboramjet.
