Valkyrie Systems Aerospace announced today that the company has officially been approved for a US Air Force research to continue development on its HoverJet Guardian. This concept is basically a hybrid eVTOL and high-speed jet system designed to provide the high speeds of jet aircraft as well as the maneuverability of Vertical Take-Off and Landing (VTOL) systems. It can be opereated in three different modes: aircraft, hovercraft, and amphibious.
The aircraft itself boasts four propellers for take-off and landings, but once airborne, it automatically switches over to two Pratt & Whitney 545c turbofan engines with a combined 8,200 pounds of horizontal thrust for propulsion. This enables the Hoverjet Guardian to maintain a cruise speed of 340 mph and a transonic top speed of 700 mph in horizontal flight mode. When fully charged, it’s good for 15 hours of endurance flight at altitudes of up to 40,000 feet.
