All of these elements focused on enabling a safe, quiet, and efficient civil tiltrotor transport. The project consisted of major experimental efforts that included.

NASA/Army/Bell XV Tiltrotor Low Noise Terminal Area Operations Flight Research Program Conner. Goal achievement would enable low-noise, safe operations for a forty-passenger commuter aircraft. V–22 technology was chosen as the baseline. I am pleased to say that the SHCT noise reduction goal of 12–dB from the baseline has been significantly exceeded. The JT8D turbofan engine, widely used in short and medium range transport aircraft, contributes substantially to airport community noise. The jet noise is predominant in the JT8D engine and may be reduced in a modified engine, without loss of thrust, . For example, the NASA Short-Haul Civil Tiltrotor (SHCT) Program was a seven-year effort (beginning in ) that focused on several elements: efficient, low-noise proprotors; low-noise terminal area approaches; contingency power, and technology integration.
