On Thursday, 15 July, the first DeltaHawk DH160A4 (inverted) engine assembled from production
parts roared to life in Racine, Wisconsin. This is the latest milestone in DeltaHawk's march
to commercial production later this year. The pre-production test engine was built with parts
produced by Kurt Manufacturing, DeltaHawk's aerospace manufacturing partner. This engine is
among the last engines to be assembled and tested by DeltaHawk before engine production is
permanently transferred to Kurt's state of the art facilities in Minneapolis, Minnesota.
Dynamometer testing and break-in were performed at DeltaHawk's R&D complex on John H. Batten Airport in Racine. This initial test run of the first inverted engine with a purpose-built block was flawless. The hour-long run consisted of continuous operation at various loads for break-in and at full load to establish the engine's rated output. All performance and system objectives were met during the test.
The engine has been delivered to a development partner for installation in a proof of concept
airframe. A second DH160A4 engine will begin endurance testing in mid-July.
