Summary The US Army is concerned about the effects of step-changes in airplane weight on wind and turbulence behind the aircraft. This affects the safety of air drops of material and personnel in the battlefield. It is particularly associated with air-drops of heavy packages from the Army's C-17 aircraft. Army scientists have developed analytical models to estimate these changes, but are in need of in-situ measurements to validate their models.
The NPS Twin Otter research aircraft will deploy to Yuma, AZ to measure winds and turbulence behind a C-17 before and after air-drops, under various conditions of atmospheric stability. It will be instrumented with its radome gust probe, its thermodynamics instrument package, aerosol probes, and carry the Twin Otter Doppler Wind Lidar (TOWDL). The Twin Otter team will deploy to Yuma for a 2 week period in July 2017.
