Excerpt from Flight Investigation of Wing-Gun Fairings on a Fighter Type AirplaneThe instruments used in all the tests were a record ing air-speed meter installed on the airplane air~speed line and a three-element control-position recorder record ing the movements of the elevator, rudder, and ailerons. Tufts were installed on the upper surfaces of the wings and in some cases in the immediate vicinity of the gun fairings to aid in the study of the behavior of the air plane at the stall.The locations of the two 0. 50 - caliber machine guns in each win are illustrated in figure 2. Figures 3 through 7 are photographs of tne various types of gun fair ings tested. In figure 3(e) are shown the submerged gun in its unfaired condition and Jhe projecting gun fitted with the fairing submitted by the Grumman Company. The Grumman fairing resembles an engine cowl in appearance except that the space between the gun barrel and the fair~ ing was sealed with rubber grommet. Figure 3(b} shows the projecting gun in its unfaired conditi n with the sub merge 1 gun removed. The Grumman fairing which was the only fairing used on the projecting guns was at first tested as submitted. In later tests the grommet was re moved and the edge of the opening was bent in so as to provide an annular space about inch in width around the gun barrel for the entry of cooling air.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
