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.

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. Determining the applicability of these criteria and gaining insight into the flying qualities of a large, supersonic aircraft are attempted. Where appropriate, YF-12, X-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 the 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, [omitted]. 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.

Developed in the 1960s/1970s, the Tu-144 was the Soviet Union's only practical venture into supersonic commercial aviation. Though its career was all too brief, it was a major technological achievement for the Soviet aircraft industry. The book provides in-depth coverage of the Concordski, including projected versions, the Tu-144's production and service history, and a comparison with the Concorde. First flown on the last day of 1968 ahead of the Concorde the Tu-144 had to undergo a long gestation period before the production version entered service in November 1977. Unfortunately, its career proved to be brief; two accidents and a powerful anti-Tu-144 lobby caused the type to be withdrawn in May 1978. The book describes the Tu-144's versions (including the Tu-144LL research aircraft developed under a Russian-U.S. program) and touches on the projected military derivatives. It is illustrated with color side views and previously unpublished photographs. -- Publisher marketing.
