Aerodynamic Characteristics of a Slot-Lip Aileron and Slotted Flap for Dive Brakes (open access)

Aerodynamic Characteristics of a Slot-Lip Aileron and Slotted Flap for Dive Brakes

From Introduction: "As a part of this investigation, a study is being made of test results obtained during the development of devices designed primarily for other purposes, such as high lift or lateral control, but which may also be used for dive control. These results have been reanalyzed and are herein presented in a form that should make them convenient for design purposes."

Tail-load measurements on the XB-15 bomber in gusty air (open access)

Tail-load measurements on the XB-15 bomber in gusty air

Report presenting some statistical measurements of the accelerations encountered in gusty air over a period of years in order to determine the loads to which airplanes may be subjected. The statistical measurements have been evaluated to yield either effective or true gust velocities as applied to the wings of airplanes.

Wind-Tunnel Investigation of a Plain and Slot-Lip Aileron on a Wing With a Full-Span Slotted Flap (open access)

Wind-Tunnel Investigation of a Plain and Slot-Lip Aileron on a Wing With a Full-Span Slotted Flap

Report presenting an investigation of a slot-lip aileron and a plain aileron singly and in combination with an NACA 23012 wing with a full-span slotted flap. Static rolling, yawing, and hinge moments were determined and are presented for several angles of attack and flap deflection.

Preliminary Report on Flight Tests of an Airplane Having Exhaust-Heated Wings (open access)

Preliminary Report on Flight Tests of an Airplane Having Exhaust-Heated Wings

Report presenting testing of an airplane in icing conditions to determine the effect of exhaust heat applied to the wings as a means of preventing ice formations. Other ice-prevention equipment, including an exhaust gas-heated pitot-static head, hot-air-heated windshield, and an inflatable de-icer were also tested.
