Like NASA, the Air Force Space Division (AFSD) and the Aerospace Corporation perform noise measurements for community noise, on vehicle loads, and/or support structure loads assessments in support of military satellite programs, as do large rocket engine manufacturers including ATK Launch Systems (Morton-Thiokol) and UTC's Rocketdyne. Private space launch vehicle companies such as Orbital Systems Corporation, United Space Alliance, and Space Exploration Technologies are poised for growth. All of these companies will benefit from the improved technology that the energy-based probe presents. In addition, Jet engine manufacturers including Rolls-Royce (with its outdoor test facility at Stennis Space Center), UTC Pratt & Whitney, and GE Aviation perform jet engine source-noise characterization. Helicopter manufacturers Boeing, Bell, and UTC Sikorsky, as well as heavy machinery manufacturers (e.g. Caterpillar, Komatsu, John Deere) are another potential user group. As system development occurs during Phase II, alternative applications will be explored to expand the customer base.
