Book Longitudinal Handling Qualities of the Tu 144ll Airplane and Comparisons with Other Large Supersonic Aircraft

Download or read book Longitudinal Handling Qualities of the Tu 144ll Airplane and Comparisons with Other Large Supersonic Aircraft written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-04 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four flights have been conducted using the Tu-144LL supersonic transport aircraft with the dedicated objective of collecting quantitative data and qualitative pilot comments. These data are compared with the following longitudinal flying qualities criteria: Neal-Smith, short-period damping, time delay, control anticipation parameter, phase delay (omega(sp)*T(theta(2))), pitch bandwidth as a function of time delay, and flight path as a function of pitch bandwidth. Determining the applicability of these criteria and gaining insight into the flying qualities of a large, supersonic aircraft are attempted. Where appropriate, YF-12, XB-70, and SR-71 pilot ratings are compared with the Tu-144LL results to aid in the interpretation of the Tu-144LL data and to gain insight into the application of criteria. The data show that approach and landing requirements appear to be applicable to the precision flightpath control required for up-and-away flight of large, supersonic aircraft. The Neal-Smith, control anticipation parameter, and pitch-bandwidth criteria tend to correlate with the pilot comments better than the phase delay criterion, omega(sp)*T(theta(2)). The data indicate that the detrimental flying qualities implication of decoupled pitch-attitude and flightpath responses occurring for high-speed flight may be mitigated by requiring the pilot to close the loop on flightpath or vertical speed.Cox, Timothy H. and Marshall, AlisaArmstrong Flight Research CenterSUPERSONIC AIRCRAFT; TU-144 AIRCRAFT; FLIGHT CHARACTERISTICS; DATA ACQUISITION; CONTROLLABILITY; BANDWIDTH; PILOT RATINGS; AIRCRAFT PERFORMANCE; SUPERSONIC TRANSPORTS; TRANSPORT AIRCRAFT; B-70 AIRCRAFT; SR-71 AIRCRAFT; FLIGHT PATHS; YF-12 AIRCRAFT

Book excerpt: Four flights have been conducted using the Tu-144LL supersonic transport aircraft with the dedicated objective of collecting quantitative data and qualitative pilot comments. These data are compared with the following longitudinal flying qualities criteria: Neal-Smith, short-period damping, time delay, control anticipation parameter, phase delay [omitted], pitch bandwidth as a function of time delay, and flightpath as a function of pitch bandwidth.

Book A Qualitative Piloted Evaluation of the Tupolev Tu 144 Supersonic Transport

Download or read book A Qualitative Piloted Evaluation of the Tupolev Tu 144 Supersonic Transport written by Robert A. Rivers and published by . This book was released on 2000 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two U.S. research pilots evaluated the Tupolev Tu-144 supersonic transport aircraft on three dedicated flights: one subsonic and two supersonic profiles. The flight profiles and maneuvers were developed jointly by Tupolev and U.S. engineers. The vehicle was found to have unique operational and flight characteristics that serve as lessons for designers of future supersonic transport aircraft. Vehicle subsystems and observed characteristics are described as are flight test planning and ground monitoring facilities. Maneuver descriptions and extended pilot narratives for each flight are included as appendices.
