Supersonic and hypersonic UAS will give the U.S. military and its allies unprecedented capability against America's near-peer adversary.
Affordable UAS capabilities give the U.S. and its allies the opportunity to boost stockpiles of hypersonic drones.
The technology paves the way for a spaceplane, which can take off and land from any runway in the world.
The technology powering the partnership
Each company will bring cutting-edge technologies to the partnership:
Cummings Aerospace's Hellhound™ UAS: A versatile unmanned aircraft with multiple specialized variants. For this partnership, Cummings Aerospace will develop a new version designed to accommodate a hypersonic-capable engine. Key features include:
Affordability, thanks to its 3D-printed modular design and commercial off-the-shelf hardware
Rapid payload swaps in fewer than five minutes, with no tools required
ATRX's Air Turbo Rocket (ATR):
A high-speed, air-breathing propulsion system
Capable of flying at hypersonic speeds, 5 times the speed of sound
Completed multiple prototype tests
Leadership perspectives
"The modern battlefield demands systems that are capable of flying faster and further into contested airspace," said Sheila Cummings, CEO of Cummings Aerospace. "This partnership with ATRX will allow us to develop ATR-powered UAS that can offer both of these characteristics in a single vehicle, at an affordable price."
"Cummings Aerospace is the perfect partner, considering the impressive work they've already done for the U.S. DOD. We're excited about this partnership because it will significantly simplify flight testing of our ATR engines," said ATRX CEO, Felix Bustos III. "Being able to validate the performance of our ATRs using a bespoke UAS based on a flight-proven airframe will de-risk and accelerate our spaceplane development efforts. Spaceplanes are very much needed with more than 50,000, mostly commercial, satellites that need to be launched into orbit in the next few years."
"Huntsville has a talented and capable space-focused workforce, and we plan to draw on their abilities to help this city become the hypersonic and spaceplane manufacturing capital of the world," Bustos said.
What's next
The companies plan to integrate the ATR engine into a Hellhound variant designed for high-speed flight and begin subsonic and supersonic flight testing.
