The U.S. Protection Superior Analysis Tasks Company (DARPA) carried out a fourth profitable take a look at flight of its Hypersonic Air-breathing Weapon Idea (HAWC) car, bringing this system to a detailed.
The HAWC take a look at car was deployed from a Boeing B-52 Stratofortress airplane, at which level its rocket booster ignited, propelling the craft to a pace at which its scramjet engine ignited. As soon as in flight, the HAWC vehicle flew for over 300 nautical miles (556 kilometers) and reached altitudes increased than 60,000 ft (18.3 km), in keeping with a DARPA statement (opens in new tab). The company didn’t give a location or date for the take a look at, stating solely that it occurred in January 2023.
DARPA added that this take a look at marks the completion of the HAWC program, one which “completed all of its preliminary aims.” DARPA will now use the information gathered from these 4 flight exams with a brand new program, Extra Alternatives with HAWC (MOHAWC), so as to construct and fly extra hypersonic test vehicles with the purpose of creating a craft that will likely be acquired and utilized by the U.S. army.

Lockheed Martin, who with Aerojet Rocketdyne developed the model of the HAWC weapon flown on this most up-to-date flight take a look at, issued its own statement (opens in new tab) praising this system’s success. “Each of our HAWC flight exams launched from an operational plane and matched efficiency fashions and predictions to assist reasonably priced, speedy improvement of future hypersonic weapons,” Lockheed Martin vp John Clark mentioned within the assertion.
Already, U.S. army officers are proclaiming the success of the HAWC program. “This month’s flight added an exclamation level to probably the most profitable hypersonic airbreathing flight take a look at program in US historical past,” Walter Value, an Air Drive deputy for the HAWC program, mentioned in DARPA’s assertion. “The issues we have discovered from HAWC will definitely improve future U.S. Air Drive capabilities.”
The important thing know-how being examined all through the HAWC program is its air-breathing scramjet engine. A scramjet is a sort of jet engine through which combustion takes place whereas the air passing via it’s transferring at supersonic speeds. Whereas typical jet engines use transferring generators to compress the air inside them, scramjets use their very own geometry and pace to attain this compression. Scramjets are designed to be extra environment friendly than different sorts of jet engines and may scale back total weight by eradicating transferring components reminiscent of turbine blades.
The info obtained from the HAWC exams will likely be used to additional hypersonic car designs within the MOHAWC program. In response to a 2022 report from C4ISRNET (opens in new tab), the follow-on program will work to enhance scramjet propulsion know-how, scale back subsystem element dimension, and enhance manufacturing processes.
The completion of the HAWC program provides to different current successes the U.S. army has had in its efforts to develop and discipline an operational hypersonic weapon. In December 2022, america Air Drive introduced it had successfully fired its first totally operational hypersonic missile, assembly all take a look at aims.
