Northrop Grumman, in collaboration with the Defense Advanced Research Projects Agency (DARPA), has unveiled an innovative prototype of the stealth drone XRQ-73, equipped with a revolutionary hybrid electric propulsion system.
The image of the XRQ-73 was released on the corporation’s official website, marking a significant advancement in the SHEPARD program – Series Hybrid Electric Propulsion AiRcraft Demonstration.
Objective and Technological Innovation
The development of the XRQ-73 aims to demonstrate and test the latest technology in hybrid-electric engines for aircraft. According to a DARPA statement, the project uses the GHO hybrid propulsion system and components from its predecessor, the XRQ-72A Great Horned Owl, developed in the 2010s.
The innovative technology replaces the traditional jet engine with a generator and electric motors that produce thrust. This approach offers better efficiency, low noise levels, and a smaller thermal footprint from the electric turbines, significantly enhancing the stealth capabilities of the reconnaissance drone.
Features and Design
The XRQ-73 is identified as a reconnaissance aircraft, as indicated by its XRQ-73 designation, with the letter “X” highlighting that it is a prototype. The fuselage design as a “tailless” flying wing, similar to the stealth bombers B2 and B21 Raider and the jet reconnaissance drones RQ-170 Sentinel, adds even more stealth to the drone.
Technical Parameters and Tests
Although the technical details of the XRQ-73 have not been disclosed, it is known to weigh 570 kg. DARPA classifies it as a group 3 drone, capable of reaching speeds between 180 and 460 km/h and flying at altitudes below 5500 meters.
Project Future
Northrop Grumman announced that DARPA plans to begin the scheduled flight tests of the prototype by the end of this year. The use of technical solutions from the previous project and some used units in the SHEPARD project should accelerate the development of a series product, with the first flight expected within the next 20 months.
