Phase I

Contract Number: W911QX-18-P-0068
Start Date: 5/21/2018    Completed: 12/23/2019
Phase I year
2018
Phase I Amount
$150,000
The Department of Defense desires to develop and produce a reliable turbocharger for an aviation compression-ignition engine with a maximum power of 180 hp at sea level which additionally provides 60% of maximum sea level power at 30,000 ft.The challenge is to reliably provide adequate manifold pressure to achieve the desired power at altitude.Diesel engines with existing standard turbocharger technology experience a significant impact on combustion and performance at altitudes above 10,000 ft., and cannot achieve the 30,000 ft. objective at 108 HP.Based upon 20 years of successful aviation turbocharging history and over 50,000 fielded aviation turbochargers, Hartzell Engine Technologies will design and develop a lightweight turbocharger that meets the required performance and reliability specifications Department of Defense UAV's using compression-ignition engines.
