The ATREX engine (Air Turbo Ramjet Engine with eXpander cycle) developed in Japan is an experimental precooled jet engine that works as a turbojet at low speeds and a ramjet up to mach 6.0. ATREX uses liquid hydrogen fuel in a fairly exotic single-fan arrangement. The liquid hydrogen fuel is pumped through a heat exchanger in the air-intake, simultaneously heating the liquid hydrogen and cooling the incoming air. This cooling of the incoming air is critical in achieving a reasonable efficiency. The hydrogen then continues through a second heat exchanger positioned after the combustion section, where the hot exhaust is used to further heat the hydrogen, turning it in a very high pressure gas. This gas is then passed through the tips of the fan providing driving power to the fan at subsonic

  • The ATREX engine (Air Turbo Ramjet Engine with eXpander cycle) developed in Japan is an experimental precooled jet engine that works as a turbojet at low speeds and a ramjet up to mach 6.0. ATREX uses liquid hydrogen fuel in a fairly exotic single-fan arrangement. The liquid hydrogen fuel is pumped through a heat exchanger in the air-intake, simultaneously heating the liquid hydrogen and cooling the incoming air. This cooling of the incoming air is critical in achieving a reasonable efficiency. The hydrogen then continues through a second heat exchanger positioned after the combustion section, where the hot exhaust is used to further heat the hydrogen, turning it in a very high pressure gas. This gas is then passed through the tips of the fan providing driving power to the fan at subsonic speeds. After mixing with the air, the hydrogen is burned in the combustion chamber. The development of this engine lost focus in favor of the new hypersonic precooled turbojet engine (PCTJ). (en)
  • Le moteur ATREX (Air Turbo Ramjet Engine with eXpander cycle) développé au Japon est un projet de moteur à réaction expérimental prérefroidi qui fonctionne comme un turboréacteur à faible vitesse et un statoréacteur à Mach 6,0. ATREX consomme de l'hydrogène liquide dans un agencement assez exotique à turbine simple. L'hydrogène liquide, carburant, est pompé à travers un (en), chauffant en même temps l'hydrogène liquide et refroidissant l'air entrant. Ce refroidissement de l'air entrant est essentiel pour obtenir un rendement raisonnable. L'hydrogène passe ensuite à travers un second échangeur de chaleur placé après la section de combustion, où la chaleur d'échappement est utilisée pour chauffer plus l'hydrogène, le transformant en un gaz à très haute pression. Ce gaz passe ensuite à travers les extrémités de la turbine fournissant la puissance d'entraînement de la turbine à vitesses subsoniques. Après mélange avec l'air, l'hydrogène est brûlé dans la chambre de combustion. Le développement de ce moteur a perdu le focus en faveur du nouveau turboréacteur hypersonique prérefroidi (PCTJ) . (fr)

El TSTO (siglas del inglés two stages to orbit; dos etapas hasta la órbita, en español) es un concepto de aeronave capaz de salir al borde del espacio, utilizando para su propulsión mediante el motor ATREX el aire y obtener la necesaria velocidad de escape para el vehículo espacial que forma la segunda etapa.
