This book was released on 1938 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of the wing-fuselage interferences investigation in progress in the N.A.C.A. variable-density wind tunnel, a method of eliminating the interference burble associated with critical midwing combinations was investigated. The interference burble of the critical midewing combination was shown to respond to modifications at the nose of the juncture and to be entirely suppressed with little or no adverse effect on the high-speed drag by special leading-edge fillets.

Download or read book Comparison of Vee type and Conventional Tail Surfaces in Combination with Fuselage and Wing in the Variable density Tunnel written by Harry Greenberg and published by . This book was released on 1941 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pitching and yawing moments of a vee-type and a conventional type of tail surface were measured. The tests were made in the presence of a fuselage and a wing-fuselage combination in such a way as to determine the moments contributed by the tail surfaces. The results showed that the vee-type tail tested, with a dihedral angle of 35.3 degrees, was about 71 percent as effective in pitch as the conventional tail and had a yawing-moment to pitching-moment ratio of 0.3. The conventional tail, the panels of which were all congruent to those of the vee-type tail, had a yawing-moment to pitching-moment ratio of 0.48.These ratios are in fair agreement with values calculated by methods shown in this and previous reports. The values of the measured moments were produced from 15 to 25 percent of the calculated value by fuselage interference.

Download or read book The Theoretical Lateral Motions of an Automatically Controlled Airplane Subjected to a Yawing moment Disturbance written by Frederick H. Imlay and published by . This book was released on 1941 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lateral motion resulting from a disturbance of the type produced by asymmetric loss of thrust has been determined for a hypothetical average airplane equipped with an automatic pilot. Plots of the resultant motion and the various modes that constitute the motion are presented for controls fixed and for various amounts of automatic control. The automatic control is assumed to be of a type that produces aileron deflections proportional to the angle of bank and rudder deflections proportional to the angle of azimuth. The use of an automatic control may introduce either of two modes. The first mode is primarily a rolling oscillation; the second is a poorly damped long-period oscillation in azimuth and bank . The motion following any change in trim causes the airplane to reach a state of equilibrium on a different flight heading from that existing before the disturbance and the airplane assumes a new flight attitude.

This book was released on 1947 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made in the Langley 15-foot free-spinning tunnel to determine the effect of horizontal-tail position on rudder hinge-moments at attitudes simulating spinning conditions. Hinge-moment measurements were made on an unbalanced rudder on a rectangular vertical tail for six positions of the horizontail tail. The hinge-moment measurements were supplemented by tuft tests to determine the air flow about the vertical tail.

Book excerpt: The NACA mixture analyzer was developed as a research instrument for the continuous indication of fuel-air ratios of aircraft-engine installations throughout the range of engine operation. It has been evaluated by using it to measure the mixture distribution of a nine-cylinder radial aircraft engine in flight.
