Tests of the Northrop MX-334 glider airplane in the NACA full-scale tunnel
Year: 1944
Abstract: INTRODUCTION
Tests of the Northrop MX-334 airplane have been made in the NACA full-scale tunnel at the request of the Army Air Forces, Materiel Command. The results of this investigation are of particular interest since the MX-334 is an all-wing glider-type airplane having neither a conventional fuselage nor vertical surfaces.
The primary purpose of these tests was to obtain sufficient data with which to determine the longitudinal and lateral stability and control characteristics of the airplane. In addition to the stability and control study, this memorandum report contains the results of tests that were made to (1) determine a suitable wing-tip leading-edge slat arrangement which would improve the static longitudinal stability of the airplane as well as increase the maximum lift coefficient; (2) establish a value of the minimum drag coefficient for the basic wing and determine the additional drag caused by the leading-edge slats; (3) determine the effects on the directional stability characteristics of the airplane of the addition of vertical fins; (4) measure the effectiveness of the air-operated directional control system.
