Packard DR-980, Radial 9 Engine
The Packard Diesel engine was designed and built by the Packard Motor Car Company, and won the 1931 Collier Trophy. The objective was to achieve greater safety and economy through use of heavy oil (furnace oil) as fuel. However, the engine also reputedly suffered from smell and vibration.
Issued Type Certificate No. 43 by the Department of Commerce in March 1930; the engine was publicly shown for the first time during the Detroit Aircraft Show in April 1930. Installed in a Bellanca aircraft, it set a world's non-refueled duration flight record of 84.5 hours in May 1931 at Jacksonville, Florida.
This artifact is the original Packard Diesel engine, the first compression ignition, oil-burning engine flown. The DR-980 powered such aircraft as the: Stinson SM-1DX Detroiter; Packard-Bellanca Pacemaker; Verville Air Coach; Ford 11-AT-1 Trimotor; Goodyear Defender airship; Towle FA-3 Flying boat; Stewart M-2 Monoplane; Waco Taper Wing; and Consolidated XPT-8A aircraft.
