Aerodynamic Characteristics of a 0.04956-Scale Model of the Convair F-102A Airplane at Mach Numbers of 1.41, 1.61, and 2.01

Description: "Tests have been made in the Langley 4- by 4-foot supersonic pressure tunnel at Mach numbers of 1.41, 1.61, and 2.01 of various arrangements of a 0.04956-scale model of the Convair F-102A airplane with faired inlets. Tests made of the model equipped with a plain wing, a wing with 6.4 percent conical camber, and a wing with 15 percent conical camber. Body modifications including an extended nose, a modified canopy, and extended afterbody fillets were evaluated" (p. 1).

Pressure Limits of Flame Propagation of Pure Hydrocarbon-Air Mixtures at Reduced Pressure

Description: Memorandum presenting the flammability limits of 18 high-boiling hydrocarbons at reduced pressures in a closed flame tube with hot-wire ignition. Characteristic two-lobe flammability-limit curves were demonstrated by all of the hydrocarbons. The rich limit, lean limit, and flammability range were found to decrease as the number of carbon atoms increased.

Flight Investigation of Factors Affecting the Choice of Minimum Approach Speed for Carrier-Type Landings of a Swept-Wing Jet Fighter Airplane

Description: Report presenting flight testing and analog-computer studies using flight-test results of a swept-wing jet fighter in the landing condition to determine the factors that influence a pilot to select the minimum approach speed for carrier-type landings. Many factors that influenced the pilot occurred in approximately the same speed range, and the quantitative determination of the influence of each factor was not possible. Results regarding measurement of airplane and engine characteristics, field… more

Lateral Stability Investigation at Mach Numbers From 0.8 to 1.7 of Two Rocket-Boosted Models of an Airplane Configuration With a 45 Degree Swept Wing and a Low Horizontal Tail

Description: "Rocket-boosted free-flight tests of two models of an airplane configuration having a 45 degree swept wing and a low horizontal-tail position have provided lateral stability derivatives and control effectiveness data for a Mach number range from 0.8 to 1.7. The experimental lateral stability derivatives presented are corrected to rigid conditions and compared with theoretically calculated rigid derivatives. The results are presented without detailed analysis" (p. 1).

Theoretical Determination of Low-Drag Supercavitating Hydrofoils and Their Two-Dimensional Characteristics at Zero Cavitation Number

Description: "The linearized theory of Tulin and Burkart for two-dimensional supercavitating hydrofoils operating at zero cavitation number is applied to the derivation of two new low-drag configurations. These sections were derived by assuming additional terms in the vorticity distribution of the equivalent airfoil; in particular, three and five terms were considered. A simplified calculation of the location of the cavity boundary streamline for arbitrary configurations is also presented" (p. 1).

Combustor performance with various hydrogen-oxygen injection methods in a 200-pound-thrust rocket engine

Description: Report presenting a determination of the characteristics velocity of liquid oxygen and gaseous hydrogen as a function of mixture ratio in a nominal 200-pound-thrust variable-length rocket engine. Fourteen injectors, which varied mixing and oxygen atomization, were investigated. The four types of injector designs included triplets of two hydrogen jets impinging on one oxygen jet, concentric injection with hydrogen surrounding a jet of oxygen, radial injection of oxygen with variations in hydroge… more

Off-Design Performance of Divergent Ejectors

Description: "The off-design performance of fixed- and of variable-geometry divergent ejectors was investigated. The ejectors, which were designed for turbojet operation at Mach 3, were investigated in the Mach number range of 0.8 to 2. The performance of a fixed-geometry ejector with high secondary-flow rates was competitive with that of more complex variable-geometry ejectors. Variable-geometry ejectors with compromises to reduce mechanical complexity produced performance reasonably close to that of an id… more
