DeltaHawk Engines is hardly a newcomer to AirVenture. It’s been showing the progression of its Jet-A 4-cylinder engine for a couple of years, but at this year’s show it’s expecting FAA certification by the end of 2019, and showed up with the 180-HP variant of the engine on a Cirrus. DeltaHawk has been making sizable improvements to the engine, and in this video Dennis Webb gave Larry Anglisano an update on the project and an overview of the latest tech.

  1. What is it now, the 25th anniversary of being 1 year from certification?

    In all seriousness, it does look like they’ve made some real progress here. And it’s impressive that something that’s been, in all honesty, vaporware, for so long, has managed to keep the lights on and attract continued funding.

    This looks like it would make a pretty good UAV engine, being jet fueled and relatively line-maintainable, which I’m sure is where they really hope to make back their investment.

    • The DeltaHawk of today (post ownership change) is worlds different from the previous incarnation that spent two decades trying to develop an engine. This engine will be certified, and it looks like it will be hard to justify a 100LL engine purchase in airframes where it is available when the time comes for overhaul. Great to see a company like this in GA committed to getting it across the finish line. Looking forward to seeing it at OSH in final form, numbers should be impressive.
