These diesel engines are is manufactured by DeltaHawk and feature a direct drive four cylinder two stroke, inverted V configuration, liquid cooling, direct injection, and turbo-diesel.
Optional Equipment includes hydraulic governor (with constant speed propeller option), a low noise exhaust (meets German noise regulations in combination with 3-blade propeller), and either a 3-blade constant speed or 2-blade fixed pitch propeller.
These firewall forward DeltaHawk engines kits are approved to operate on Diesel and Jet fuel.
The 180-hp DHK180 is the first of a family of engines to come from DeltaHawk, according to officials with the Racine, Wisconsin-based company.
Featuring an inverted-V engine block, turbocharging and supercharging, mechanical fuel injection, liquid cooling, direct drive, and 40% fewer moving parts than other engines in its category, the 180-hp DHK180 engine is a clean-sheet design secured by multiple patents, company officials noted.
According to company officials, the new engine is “highly responsive and produces more usable torque than traditional aircraft engines in its class, all while burning significantly less fuel and with a resulting lower net carbon footprint. The engine can burn both Jet-A and sustainable aviation jet fuels.
With FAA certification in hand, performance and technical upgrades were underway, along with additional endurance testing and flight evaluations in multiple aircraft.
The new engine was selected by NASA to power the hybrid propulsion system planned for its Subsonic Single Aft Engine Aircraft (SUSAN) scale flight test vehicle, a proof-of-concept electro-fan design for future regional transport aircraft. The DeltaHawk engine has also been selected by Ampaire for an upcoming aircraft testbed application in support of NASA’s Small Business Innovation Research initiative.
First deliveries were expected in 2024.
