This hydrogen-powered single-piston jet engine will revolutionize aviation and ground transportation

DeltaHawk Engines is a piston jet engine manufacturer that has passed all certification checks by the American Federal Aviation Administration (FAA). This Standard Airworthiness Certificate is the official approval that allows the operation of an aircraft with minimal restrictions, allowing its commercial use. This new hydrogen-powered engine could have a revolutionary impact on the aviation and road transport sectors. The results of tests carried out through computer simulations are promising, says their designer.

Variants of the DeltaHawk piston engine have been developed for deployment in various contexts, such as hydrogen-powered aviation, commercial road vehicles, and military mobility applications. The company is currently conducting computer simulations and testing at its headquarters in Racine, Wisconsin.

Although it was developed for aviation, smaller variants can be used in ground vehicles.

An engine that uses hydrogen eliminates the problems of the fuel cell

The technology of internal combustion engines powered by hydrogen replaces fuel cell systems, which are more expensive and rely on specific infrastructure. These are engines that are more tolerant of hydrogen impurities than fuel cells. In addition to these advantages, the most important thing, according to the company, is that it allows you to take advantage of the deep knowledge that exists in the production of internal combustion engines and the extensive service networks.

The DeltaHawk engine design has several advantages, such as reduced development costs and time to market. Thanks to the maturity of its technology, the manufacturer guarantees profitability and stability. The engine design shows a lower power reduction curve over time than those using hydrogen technology, which means greater fuel savings.

Applications beyond aviation

The DeltaHawk uses aircraft engine architecture to create variants for different applications with a compact, lightweight, and durable design. According to the manufacturer, computer simulations of these two-stroke piston engines show technological superiority over four-stroke engine architectures from other manufacturers that are also adapted to use hydrogen.

The first in the DeltaHawk family of fuel cell engines is the DHK180, capable of developing a power of 180 HP. Ease of handling, high performance, efficiency at high altitude, and low maintenance costs are the calling cards of this technology that takes advantage of the conventional piston engine. Recently, the DHK180 was selected by NASA for its Subsonic Single Aft Engine project, known as SUSAN, and Ampaire was also selected to be deployed to test a concept hybrid aircraft.
