Download or read book Analysis of the Effects of Boundary-layer Control on the Take-off Performance Characteristics of a Liaison-type Airplane written by Elmer A. Horton and published by . This book was released on 1948 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: A performance analysis is given to determine whether bondary-layer control by suction might reduce the minimum take-off distance of a four- or five-place airplane. Results indicate that boudary-layer control might be effective in improving the take-off characteristics of this type airplane having wing loading of 10 or more pounds per square foot and aspect ratios of 10 or more.

Horton and published by . This book was released on 1950 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made to determine the effects of boundary-layer control on the landing performance characteristics of a liaison type of airplane having a payload of 1500 pounds and a flight duration of 5 hours. The aspect ratio was varied from 5 to 15, the wing span from 30 to 100 feet, and the brake horsepower from 300 to 1200. The use of boundary-layer control caused reduction in total landing distance (25 to 40 percent), ground-run distance, gliding speed, and stalling speed whereas sinking speed was increased only slightly.

This book was released on 1947 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: A performance analysis has been made to determine whether boundary-layer control by suction might reduce the minimum take-off distance of a four-place or five-place liaison-type airplane below that obtainable with conventional high-lift devices. The airplane was assumed to be capable of operating from airstrips having a ground friction coefficient of 0.2. The pay load was fixed at 1500 pounds and the wing span was varied from 30 to 100 feet, the aspect ratio from 5 to 15, and the power from 200 to 1300 horsepower. Maximum lift coefficients of 5.0 and 2.8 were assumed for the airplanes with and without boundary-layer control, respectively. A conservative estimate of the boundary-layer-control-equipment weight was included. The effects of the boundary-layer control on total take-off distance, ground run, and stalling speed were determined The analysis indicates that the addition of boundary-layer control does not reduce the absolute minimum total take-off distance that is obtained with an airplane having a low wing loading and a moderately low aspect ratio. The effectiveness of boundary-layer control in reducing the total take-off distance for a given maximum speed improves with increasing aspect ratio and, for wing loadings of 10 pounds per square foot or more and an aspect ratio of 10 or more, the addition of boundary-layer control results in a decrease in the total take-off distance. For a given maximum speed the ground run was reduced for all configurations by the addition of boundary-layer control. The reduction was negligible for aspect ratio of 5 but was 10 to 30 percent for aspect ratios of 10 and 15. The stalling speed for a given maximum speed was reduced 20 to 25 percent for all configurations by application of boundary-layer control. A reduction in the weight of the boundary-layer control equipment would result in an appreciable decrease in the total take-off and ground run distances, but would have a negligible effect on the stalling speed.

This book was released on 1948 with total page 748 pages. Available in PDF, EPUB and Kindle. Book excerpt: The landing of a simplified airplane structure, consisting of a uniform beam for the wings, a concentrated mass for the fuselage, and a linear spring for the landing gear, is analyzed exactly and is compared with several approximate solutions. The approximate solutions which neglect elasticity in the determination of landing-gear reaction but consider elasticity in computations of stresses give results of good accuracy and indicate that drop tests in which rigid masses are used may be a satisfactory approach to the landing problem.
