JUH-1H Redesigned Pneumatic Boot Deicing System Flight Test Evaluation
The U.S. Army Aviation Engineering Flight Activity conducted an evaluation of the Pneumatic Boot Deicing System (PBDS) with two pneumatic deicer boot designs, referred to as second and third generation. The objective of the test was to conduct feasibility testing of the pneumatic system concept for...
