It can run on [Jet-A](/source/Jet-A) or [sustainable aviation fuel](/source/sustainable_aviation_fuel). The manufacturer claims that it has "40 percent fewer moving parts than other engines in its category." == Development == In 2014, a DH180 was installed and demonstrated at the [EAA Airventure](/source/EAA_Airventure) airshow on a [Cirrus SR20](/source/Cirrus_SR20). A retrofit kit is planned for the SR20.{{cite journal|journal=AOPA Pilot|title=Diesels on the cusp|author=Jim Moore|page=87|date=March 2015}} The engine received its [type certificate](/source/type_certificate) from the [Federal Aviation Administration](/source/Federal_Aviation_Administration) on April 7, 2023, with first customer deliveries planned for 2024.{{cite web|url= https://www.avweb.com/ownership/engines/deltahawk-dhk180-receives-faa-certification/|title= DeltaHawk DHK180 Receives FAA Certification|access-date= 19 May 2023|last= O'Connor|first= Kate|work= AVweb|date= 18 May 2023 |archive-url= https://archive.today/20230519114959/https://www.avweb.com/ownership/engines/deltahawk-dhk180-receives-faa-certification/|archive-date= 19 May 2023|url-status= live}}{{cite web|url= https://canadianaviator.com/jet-fueled-piston-engine-certified/|title= Jet-Fueled Piston Engine Certified|access-date= 27 May 2023|work= Canadian Aviator |date= 27 May 2023|archive-url= https://archive.today/20230527110653/https://canadianaviator.com/jet-fueled-piston-engine-certified/|archive-date= 27 May 2023|url-status= live}} The US [National Aeronautics and Space Administration](/source/National_Aeronautics_and_Space_Administration) selected the engine for their ''Subsonic Single Aft Engine Aircraft'' scale flight test vehicle. ==Variants== ;DHK180 :Certified version, {{convert|180|hp|kW|0|abbr=on}} ==Applications== *[Barrows Bearhawk](/source/Barrows_Bearhawk){{cite web|url= https://www.avweb.com/aviation-news/bearhawk-makes-deltahawk-an-option/|title= Bearhawk Makes DeltaHawk An Option|access-date= 8 August 2023|last= Cook|first= Marc|work= AVweb|date= 7 August 2023|archive-url= https://archive.today/20230808112335/https://www.avweb.com/aviation-news/bearhawk-makes-deltahawk-an-option/|archive-date= 8 August 2023|url-status= live}} *[Cirrus SR20](/source/Cirrus_SR20) *[Lambert Mission 212](/source/Lambert_Mission_212) *[Van's Aircraft RV-8](/source/Van's_Aircraft_RV-8) *[Velocity XL](/source/Velocity_XL) ==Specifications (DHK180)== {{pistonspecs |ref=TCDS, AVweb and manufacturer{{cite web|url= https://www.deltahawk.com/engines/|title= Engines|access-date= 15 May 2023|author= DeltaHawk|work= deltahawk.com|archive-url= https://archive.today/20230521120713/https://www.deltahawk.com/engines/|archive-date= 21 May 2023|url-status= live}} |type=V4, two-stroke, liquid-cooled, piston, diesel aircraft engine |bore={{convert|4|in|cm|0|abbr=on}} |stroke={{convert|4|in|cm|0|abbr=on}} |displacement={{convert|202|cuin|L|0|abbr=on}} |length={{convert|33|in|cm|0|abbr=on}} |diameter= |width={{convert|24|in|cm|0|abbr=on}} |height={{convert|22|in|cm|0|abbr=on}} |weight={{convert|357|lb|kg|1|abbr=on}} |valvetrain= |supercharger=twin screw |turbocharger=yes |fuelsystem=mechanical injection, mechanical gear pump, one injection pump per cylinder |fueltype= certifies for Jet-A, Jet A-1, SAF; will also burn JP5, JP8, D1, D2, JP-8-100, F-24, |oilsystem= dry sump, external mechanical gear pump |coolingsystem=liquid |power={{convert|180|hp|kW|0|abbr=on}} at 2600 rpm, five minutes maximum for take-off; {{convert|135|hp|kW|0|abbr=on}} at 2200 rpm, continuous |specpower= |compression=20.1:1 |fuelcon=7.3 gal/hr (27.6 L/hr)at 135 HP Economy Cruise, 10.8 gal/hr (40.9 L/hr) at 180 hp |specfuelcon={{cvt|{{#expr:7.3/135round3}}|USgal/hp/h|L/kW/h}} |oilcon= |power/weight=0.50 hp/lb }} ==See also== * [DeltaHawk DH160](/source/DeltaHawk_DH160) ==References== {{Reflist}} ==External links== *[http://www.deltahawk.com/ Company website] *[https://www.youtube.com/watch?v=uSfBcE_7jx0 Video of SR20 with DeltaHawk DH180] *[https://www.avweb.com/air-shows-events/airventure/airventure-2023-deltahawk-dhk180/ Video interview at AirVenture 2023] Category:DeltaHawk aircraft engines Category:Aircraft diesel engines Category:1990s aircraft piston engines Category:V4 engines Category:Two-stroke aircraft piston engines Category:Liquid-cooled aircraft piston engines --- Adapted from the Wikipedia article [DeltaHawk DH180](https://en.wikipedia.org/wiki/DeltaHawk_DH180) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/DeltaHawk_DH180?action=history)).
