Fundamental flame velocities of pure hydrocarbons 1: alkanes, alkenes, alkynes benzene, and cyclohexane

Description: The flame velocities of 37 pure hydrocarbons including normal and branched alkanes, alkenes, and alkynes; as well as benzene and cyclohexane, together with the experimental technique employed are presented. The normal alkanes have about the same flame velocity from ethane through heptane with methane being about 16 percent lower. Unsaturation increases the flame velocity in the order of alkanes, alkenes, and alkynes. Branching reduces the flame velocity.

Transonic Drag Characteristics of a Wing Body Combination Using a Thin Tapered Wing of 45 Degrees Sweepback

Description: Report presenting tests of a wing-body combination using the free-fall method, which was made up of a fineness-ratio-12 body with a 45 degree sweptback wing, an aspect ratio of 3.75, and an NACA 65-003 airfoil section in the direction perpendicular to the 50-percent-chord line. Results regarding the complete configuration, wing, body-tail combination, and component effects on total drag are provided.
