Download or read book Measurements of the Pressure Distribution on the Horizontal tail Surface of a Typical Propeller driven Pursuit Airplane in Flight written by and published by . This book was released on 1948 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total horizontal-tail load and root bending-moment increments calculated by the use of existing rational procedures are compared with the experimental values obtained in abrupt pull-up push-down maneuvers obtained on a representative pursuit-type airplane. The computed loads were determined for the experimental motions and for two estimated linear design motions. The results showed that the actual maximum maneuvering tail loads obtainable in flight could be predicted satisfactorily from either the experimental elevator motions measured in the maneuvers of from the estimated linear elevator motions, provided that good quantitative knowledge was had of pertinent aerodynamic parameters.

This book was released on 1948 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total horizontal-tail load and the root bending moment increments calculated by the use of existing rational procedures are compared with experimental values obtained in pull-up push-down maneuvers on a representative propeller-driven pursuit-type airplane for six different combinations of power, indicated airspeed, and pressure altitude. The computed loads were determined for the experimental elevator motions, and for two estimated linear design motions. There is also presented a comparison between the computed and the experimental load distributions. Briefly touched upon are two abbreviated static methods for predicting the maximum up-loads in pull-up push-down maneuvers.

Download or read book Measurements of the Pressure Distribution on the Horizontal tail Surface of a Typical Propeller driven Pursuit Airplane in Flight written by Melvin Sadoff and published by . This book was released on 1947 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pressure-distribution measurements were made in steady straight and accelerated flight over both sides of the horizontal-tail surface of a typical pursuit airplane up to a Mach number of 0.79. The results showed that a sharply increasing down-load was required to balance the increased diving moment of the wing-fuselage-propeller group at Mach numbers above about 0.70. There was little change, up to a Mach number of about 0.65, of the tail-load gradient (rate of increase of tail load for a unit change in acceleration factor); beyond that Mach number, however, a rapid decrease of tail-load gradient to a Mach number of about 0.73 and then a very sharp increase up to a Mach number of 0.785 was noted. The root bending moments increased considerably on the right tail and decreased, to a lesser extent, on the left tail at the higher Mach numbers, resulting in increased fuselage torsional moments at high speeds. At the higher values of lift coefficient (0.5 to 0.8), there was little change of the lateral distance to the center pressure up to a Mach number of about 0.73; at the highest speed and at low lift coefficients (0 to 0.1) the center of pressure was inboard approximately 3 feet on the left tail and 1.5 feet on the right tail as compared with the values at lower speeds. It appears that satisfactory quantitative data on total tail loads may be obtained from measurements at four stations, equally spaced along the entire tail span.

This book was released on 1953 with total page 740 pages. Available in PDF, EPUB and Kindle. Book excerpt: The heating requirements for several methods of icing protection for a typical turbojet transport airplane operating over a probable range of icing conditions are evaluated, and the airplane performance penalties associated with providing this protection from various energy source are assessed. Continuous heating requirements and airplane penalties for the turbojet transport are considered considerably increased over those for lower-speed aircraft. Heating requirements can be substantially reduced by use of a cyclic de-icing system and choice of the proper energy source.

This book was released on 1930 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: This information is issued in advance of the report on the complete investigation, because of the immediate interest in tail surface loads occasioned by the results of recent tail surface pressure distribution tests and failures occurring in flight. It should serve as a guide to those designers who wish to insure structural safety in their airplanes pending the formulation of more satisfactory design rules for tail surfaces.
