Karem Aircraft Plans to Test its Optimum-speed Tiltrotor by 2019

Sometime in 2018 or 2019, Karem Aircraft will power up what it believes should be the American military’s next vertical lift system, the company’s patented optimum-speed tiltrotor.

Best known as the creator of the modern military drone, the company’s founder and namesake Abraham Karem is now devoting his attention to vertical takeoff and landing tiltrotors, with blades that rotate at the most efficient speed during all phases of hover and forward flight.

The frontrunner for this optimum-speed system was the A160 Hummingbird UAV: created by Karem’s Frontier Aircraft and later acquired by Boeing Defense, Space & Security. It demonstrated a highly efficient helicopter configuration that flew past 18h during one test.

And the ITEP engine may be the drop in for all FVL aircraft.
