United Airlines Ventures (UAV), the venture capital arm of United Airlines, has revealed an investment in aerospace start-up Astro Mechanica, a company working on adaptive propulsion and advanced airframe concepts that could enable the next generation of supersonic aircraft. These technologies carry near-term potential for applications in national defence, orbital launch, and long-range cargo transportation.
UAV, established in 2021, was created to fund early-stage companies focused on innovations that could transform aviation and travel. This latest investment aligns with its mission to support technologies that promise breakthroughs in performance, sustainability, and capability within the aerospace sector.
“Astro Mechanica is developing an adaptive engine concept for strategic military and commercial applications, addressing the challenging yet worthwhile pursuit of supersonic flight,” said Mukul Hariharan, Managing Partner at United Airlines Ventures. “UAV is excited to join Astro Mechanica’s renowned investment partners to support its exceptional management team as they advance their engine technology and progress towards their first aircraft prototype.”
Astro Mechanica’s propulsion system, named Duality™, is at the heart of its ambitions. Designed as a hybrid electric engine, it aims to optimise performance across the full spectrum of flight conditions, from initial take-off through to speeds exceeding Mach 3. The system seeks to address the limitations of existing jet engines by shifting its configuration to function efficiently as a turbofan at lower speeds, as a turbojet just below supersonic levels, and ultimately as a ramjet at higher supersonic ranges. If successful, this approach would create the first supersonic aircraft with transpacific reach, bringing both military and commercial applications within closer reach.
This development underlines how aerospace start-ups and established industry players are converging to explore supersonic travel after decades of stagnation following Concorde’s retirement. With UAV’s backing, Astro Mechanica hopes to accelerate its research and move closer to building a working prototype that could redefine high-speed aviation.
