# Hybrid Rocket Engines The SABRE Engine Concept Behaves As Both a Jet and a Rocket By Rahul Kalvapalle | Published 2015-04-27 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/sabre-engine-concept References: [gizmag](http://www.gizmag.com/sabre-engine-afrl-feasibility-study/37092/) & [reactionengines](http://www.reactionengines.co.uk/press_release.html) The [SABRE](https://www.trendhunter.com/trends/conversational-travel-booking) engine concept is a contraption that lies at the hart of the Skylon reusable space plane project being developed by Reactoin Engines. The SABRE (Synergetic Air-Breathing Rocket Engine) acts as a jet in the atmosphere and a rocket in space. This allows it to reduce the propellant load and means it doesn't need to carry as much oxygen. Once in space, the SABRE engine concept switches to rocket mode to help the space plane achieve the great speeds required to reach orbit. Reaction Engines are currently working on coming up with concept vehicles that would be able to use the SABRE engine. This project holds exciting applications for the [space launch industry](https://www.trendhunter.com/trends/dianai-solar-sailer) as well as the military. ## Trend Insights (Trend Hunter) - Score: 1.9/10 - Popularity: 30% | Activity: 19% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Science](https://www.trendhunter.com/science) ## Key Themes ### What Makes This Trend Stand Out - **Hybrid Rocket Engines:** The SABRE engine concept provides disruptive innovation opportunities in both the space launch industry and military. - **Reusable Space Planes:** The development of SABRE engines opens up opportunities for disruptive innovation in the space travel industry. - **Synergetic Air-breathing Rocket Engine (SABRE):** The SABRE engine concept offers disruptive innovation potential for both civilian and military applications. ### Sectors Adopting This - **Space Launch Industry:** The SABRE engine concept brings disruptive innovation potential to the space launch industry. - **Military:** The SABRE engine concept presents disruptive innovation opportunities for military applications. - **Aerospace:** The development of SABRE engines in the aerospace industry opens up potential for disruptive innovation. ## Related on Trend Hunter - [Rotating-Detonation Hypersonic Engines](https://www.trendhunter.com/trends/GE-Aerospace.md) - [Hydrogen-Powered Jet Engines](https://www.trendhunter.com/trends/rollsroyce-ae-2100.md) - [Revolutionary Reusable Rockets](https://www.trendhunter.com/trends/reusable-rockets.md) - [Hydrogen-Powered Hypersonic Airplanes](https://www.trendhunter.com/trends/sky-magnetar.md) - [3D-Printed Orbital Rockets](https://www.trendhunter.com/trends/phoenix-engine.md) - [Hypersonic Launch Vehicles](https://www.trendhunter.com/trends/launch-vehicle.md) - [Eco-Friendly Nano Satellites](https://www.trendhunter.com/trends/orbex-prime.md) - [Hydrogen Fuel-Cell Engines](https://www.trendhunter.com/trends/airbus.md) - [Emissions-Free eVTOL Aircraft](https://www.trendhunter.com/trends/emissionsfree-evtol-aircraft.md)
