US builds a hypersonic rocket system with green hydrogen

WASHINGTON – Hypersonix Launch Systems is creating a reusable green hydrogen launch system that will deliver small satellites into orbit, learned BulgarianMilitary.com, citing Hypersonix Launch Systems and mil.in.ua.

The company wants to reduce the cost of delivering satellites into orbit without any emissions of carbon or other harmful gases. Wirraway’s three-stage launch system consists of a reusable Delta Velos orbital rocket and a Boomerang first-stage reusable launch vehicle.

Boomerang must accelerate the Delta Velos orbiter to Mach 5 before separating and returning to base. Then the orbiter will continue to move, accelerating from 5 to 12 Mach, and will go to the upper atmosphere, where it will release a payload – a satellite weighing 50 kg, which will be accelerated to Earth. The orbiter will then return to base, landing like a normal aircraft.

The Delta Velos Orbiter will be equipped with four Hypersonix Spartan engines, which the company says are the result of 30 years of research and more than 6,000 ground launches and 11 suborbital fields under HiFiRe and HyShot.

The Spartan engine is reusable, made from a ceramic matrix composite printed on a 3D printer using next-generation additive manufacturing technology at the University of Sydney. It also provides carbon-neutral traction as it is powered by hydrogen produced by solar energy and emits only water vapor.

2024

The team hopes that Delta Velos Orbiter will take to the air around 2024. The company will start with a smaller device to test the effectiveness of the launch system, as well as speed, reusability, and range of vehicle design, starting with the Dart AE, a scaled-down technology demonstrator about 2.8 meters long.

It will be equipped with a Spartan engine and must have a range of 500 km. It will be followed by a larger Delta Velos demonstrator. With a length of 5.5 m, a wingspan of 2 m, and a fuselage diameter of 0.6 m, it will be equipped with four direct-jet air-jet engines, providing a flight range of 2500 km and a maximum speed of Mach 12.

After testing the design, the Delta Velos orbital will appear in full length with a length of 12 m, a wingspan of 3.5 m, and a diameter of 1 m.

Because Orbiter is designed to work with any accelerator that allows it to be launched from any launch site after Delta Velos takes off, Hypersonix will develop the Boomerang accelerator in partnership with an existing missile manufacturer.

Although the choice of technology has not yet been determined, the company plans to launch the Boomerang launch vehicle on clean water.
