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.
SABRE (Synergetic Air Breathing Rocket Engine [4]) was a concept under development by Reaction Engines Limited for a hypersonic precooled hybrid air-breathing rocket engine. [ 5 ] [ 6 ] The engine was designed to achieve single-stage-to-orbit capability, propelling the proposed Skylon spaceplane to low Earth orbit.
In July 2012, United Technologies Corporation agreed to sell Pratt & Whitney Rocketdyne to GenCorp,Inc., which also owns rocket engine producer Aerojet. [1] [2] [3] The sale was completed in June 2013, when the company was merged with Aerojet to form Aerojet Rocketdyne. [4]
OrbitX was established on June 2, 2019 as OrbX, [1] a private venture by a group of youth including Dexter Baño Jr., Enzo Victor, and Paulo Sairel. [2] OrbitX's short term goal is to develop the first indigenous reusable rocket, and the long-term goal is to send the first Filipino to Mars and back. [3]
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.
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.

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]
