Aspects of Pilot Decision Making

Description: Report presenting results of a detail analysis of the tasks performed by the pilot of a modern airborne weapons system. The analysis is coded and presented in diagrammatic form to show alternative courses of action that may result in successful completion of a mission phase. (Abstract)

Boundary Layer Control Applied to Tail Surfaces of Aircraft, Part 1. Wind Tunnel Report

Description: Report describing the wind tunnel tests of a model of a horizontal tail surface equipped with low pressure high lift boundary layer control made to determine life, drag, pitched moment, hinge moment coefficients, and chordwise pressure distributions for various angles of attach, elevator deflections, and blowing quantity flow coefficients.

Boundary Layer Control Applied to Tail Surfaces of Aircraft, Part 2. Final Report

Description: Report presenting the results of flight tests to determine the effects of blowing boundary layer control applied to the tail surfaces of the Cessna Model 319B. The design, construction, structural text and installation of BLC tail surfaces are described, as well as the flight test results, including numerous graphical depictions of the results.

Mechanical Properties of Selected Alloys at Elevated Temperatures, Part II: Design Criteria of Silicon Carbide

Description: Report describing a research study to determine in broad parameters the areas where a brittle, non-metallic body such as silicon carbide might be used in aircraft construction and establishing methods for obtaining these properties. A theoretical and literature review, design parameters, discussion of the testing phase, and test specimen geometry explanation are included.

Mechanical Properties of Selected Alloys at Elevated Temperatures [Pt. 1]

Description: Report describing a research study to provide material property data of the type and quality necessary for efficient design of hot aircraft and missile structural components. Six materials in plate and bar form were subjected to tension, compression, bearing, and shear stresses at various temperatures. Preliminary considerations of the study, testing apparatus, calibration and accuracy of the equipment, testing procedures and results are discussed.

Survey of Human Dynamics Data and a Sample Application

Description: Report describing an approach to the application of the results of research on the human transfer function. A form of a quasi-linear human transfer function has been laid out on the basis of previous experimental results. It has been assumed that human reaction time and neuromuscular lag are constant and that the pilot will adopt a gain and compensation through training which will minimize the mean square tracking error of the system of which he is part. Calculations were made of the mean squar… more
