    The ‘ patent relates to the use of multiple low-noise block converter feedhorns, or LNBFs, which are antennas used for satellite reception. On Ap , the US Patent and Trademark Office issued an order granting reexamination of the ‘ patent.   In , an XV dazzled a Paris Air Show audience that included Secretary of the Navy John Lehman, with a demonstration of takeoffs and landings, low- speed maneuvers, degree turns and high-speed flyovers. The XV’s Paris Airshow debut was the catalyst for the next generation of tiltrotors.

After being used to qualify the design, NASA heavily modified the aircraft for continuing research. Boeing SR. several elements: efficient, low-noise proprotor, low-noise terminal area approaches, contingency power, and technology integration.

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

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.

SeaWiFS produced two types of science data: local area coverage (LAC) and global area coverage (GAC). The LAC provided coded data collected from the local area under the spacecraft’s flight path within a 1,mile (2,kilometer) swath, with three quarters of a mile ( kilometers) as the smallest visible area.
