Aircraft program
High-lift, VTOL demonstrator aircraft for (DARPA) SPeed and Runway INdependent Technologies (SPRINT) X-Plane Demonstration Project, aiming to have a cruise speed of 400-450 KTAS and requires an ability to hover. In development.
The aircraft as engineered: what it is built from, the systems it flies with, and its configuration — each box a theme.
Technical reference compiled with AI research; a value appears only where two independent research passes and a web fact-check agree. Gaps are deliberate.
