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. 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.
Aerojet Rocketdyne proposed in 2014 to "lobby the government to fund an all-new, U.S.-sourced rocket propulsion system." In June 2014, Aerojet initially projected it would cost under US$25 million per pair of engines, not including the up to US$1 billion estimated development cost to be funded by the government.

Unlike conventional superchargers and turbos, no engine power would be used to supply the extra air, and testing on a Chevy 409 engine was reported to give a power gain from 405 hp (302 kW) to 835 hp (623 kW) with the supercharger engaged. [4] [7] Rocket thrust engines, in various sizes. The "T-16" had 300 lbf (1,300 N) of thrust.
A rocket turbine engine is a combination of two types of propulsion engines: a liquid-propellant rocket and a turbine jet engine. Its power-to-weight ratio is a little higher than a regular jet engine, and works at higher altitudes. [1] [2] [3]
The RBCC, or rocket-based combined cycle propulsion system, was one of the two types of propulsion systems that may have been tested in the Boeing X-43 experimental aircraft. The RBCC, or strutjet as it is sometimes called, is a combination propulsion system that consists of a ramjet , scramjet , and ducted rocket , where all three systems use ...
An airbreathing jet engine (or ducted jet engine) is a jet engine in which the exhaust gas which supplies jet propulsion is atmospheric air, [1] which is taken in, compressed, heated, and expanded back to atmospheric pressure through a propelling nozzle. [2]
RS-68 being tested at NASA's Stennis Space Center Viking 5C rocket engine used on Ariane 1 through Ariane 4. A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket.
