Ursa Major has successfully tested the Draper hypersonic rocket engine fuelled by hydrogen peroxide and paraffin

Last May, US startup Ursa Major signed a contract with The U.S. Air Force Research Laboratory to develop and produce a propulsion system for hypersonic testing. A year later, the company tested the Draper engine.

Here's What We Know

Previously, the startup gave the Pentagon the Hadley engine for hypersonic launches. The developments from this project were used to create the Draper propulsion system. The engine uses hydrogen peroxide and paraffin as fuel.

The Draper has a thrust of 1.8 tonnes at sea level. The propulsion system is expected to be used not only in spacecraft but also in anti-satellite systems.

Last year Ursa Major also signed a contract to develop the Arroway engine. It will be a replacement for Russian RD series propulsion systems. Fire tests of Arroway will begin next year.
