liquid-hydrogen(-fueled) rocket engine
41Physical Sciences — ▪ 2009 Introduction Scientists discovered a new family of superconducting materials and obtained unique images of individual hydrogen atoms and of a multiple exoplanet system. Europe completed the Large Hadron Collider, and China and India took… …
42Single-stage-to-orbit — The VentureStar was a proposed SSTO spaceplane. A single stage to orbit (or SSTO) vehicle reaches orbit from the surface of a body without jettisoning hardware, expending only propellants and fluids. The term usually, but not exclusively, refers… …
43Ramjet — A ramjet, sometimes referred to as a stovepipe jet, or an athodyd, is a form of jet engine that contains no major moving parts. Unlike most other airbreathing jet engines, ramjets have no rotary compressor at the inlet, instead, the forward… …

48Spaceplane — A Space Shuttle rocketing into space, just after booster separation. A spaceplane is a vehicle that operates as an aircraft in Earth s atmosphere, as well as a spacecraft when it is in space. It combines features of an aircraft and a spacecraft,… …
49Alternative fuel vehicle — refers to a vehicle that runs on a fuel other than traditional gasoline or diesel; any method of powering an engine that does not involve solely petroleum (e.g. electric car, gasoline electric hybrid, solar powered). Due to a combination of heavy …
50Scramjet programs — This page describes a number of research and testing programs for the development of supersonic combustion ramjets (scramjets) Many of these programs have their own pages, but an attempt is made here to provide a short overview of a large number… …
