Tests of a 1/7-Scale Powered Model a Twin-Boom Airplane and a Comparison of Its Stability, Control, and Performance With Those of a Similar All-Wing Airplane

Abstract

An investigation of a 1/7 scale powered model of a twin-boom airplane in the Langley full-scale tunnel was conducted in order to obtain a comparison of its stability, control, and performance characteristics with those of an all-wing airplane design of the same over-all proportions. These models represent very large airplanes having a gross weight of nearly 90 tons, a wing span of 290 feet, and an aspect ratio of 10.6. The test results of the all-wing design have been previously reported, and estimated flying qualities of this design have been prepared in an unpublished paper. The test results of the twin-boom model are presented in this paper together with a summary comparison of the characteristics of the two types of airplane.
