ザ ルサック-11 (レペールアメリカ陸軍戦闘)は、初期のアメリカの2人乗り戦闘機でした。それはフランスのデザインで、第一次世界大戦中にアメリカで委託され、建造され、アメリカ陸軍航空隊によって大量に命じられましたが、これらは戦争の終わりにキャンセルされ、わずか30が建設されました。このタイプは実験目的で使用され、1920年代にいくつかの高度記録を設定しました。

A French Design with American Muscle
ザ Packard LePère LUSAC-11 (Lepère United States Army Combat) was a two-seat fighter designed by Captain Georges LePère of the French Air Service for production in the United States. While it arrived too late to see combat in World War I, it became a legendary testbed in the early 1920s. Armed with the powerful American Liberty Engine, it was one of the fastest and highest-climbing aircraft of its era, serving as the platform for pioneering research into high-altitude flight and turbocharging.

Engineering for the Stratosphere
- The Liberty Engine Integration: Unlike many contemporary biplanes that used lower-powered rotary engines, the LUSAC-11 was designed specifically around the liquid-cooled Liberty L-12. This engine provided a massive power-to-weight ratio for the time.
- Veneer Fuselage: The aircraft featured a plywood-veneer monocoque fuselage, which was much stronger and more aerodynamic than the traditional fabric-on-wood-frame construction used on most WWI fighters.
- Turbo-Supercharging Research: The LUSAC-11 was famously used by Dr. Sanford Moss to test the first exhaust-driven turbo-superchargers. This allowed the engine to maintain power even as the air thinned at high altitudes.
- Staggered Wings: The biplane wings were staggered to improve the pilot’s visibility and aerodynamic efficiency, a hallmark of LePère’s clean French design philosophy.
A Legacy of Records
- Shattering the Ceiling: On September 28, 1921, Lieutenant John A. Macready flew a specially modified LUSAC-11 to a world-record altitude of 34,509 feet. At this height, the air was so thin and cold that Macready required a primitive supplemental oxygen system.
- The McCook Field Era: Most LUSAC-11s spent their careers at McCook Field in Ohio, the center of U.S. Army Air Service engineering. They were used to test everything from new propellers to early flight instruments.
- Late to the Fight: Of the 3,500 units originally ordered, only about 25 were completed before the Armistice led to mass cancellations. Only two were actually shipped to France before the war ended.
- Survivor: The only remaining LUSAC-11 is a centerpiece of the National Museum of the United States Air Force in Dayton, Ohio, restored to represent the aircraft used in the 1921 record flight.
