Combustion efficiency of homogeneous fuel-air mixtures in a 5-inch ram-jet-type combustor
Report presenting combustion-efficiency data for a 5-inch-diameter combustor employing a straight V-gutter flame holder and a simple cone flame holder. The data covers a range of inlet static pressures, temperatures, and velocities for four fuels. The majority of the data indicated that the combustion efficiency was relatively insensitive to fuel-air ratio over the range of fuel-air ratios investigated.

Investigation of ram-jet afterburning as a means of varying effective exhaust nozzle area
Report presenting a discussion of the flow mechanism in an afterburner extension to a ramjet engine. An experimental evaluation of the operation of 16-inch ramjet equipped with an afterburner at Mach number 1.8 and 2.0 in the supersonic wind tunnel. The experimental data confirmed the proposed method of afterburner operation.

MTA, A-12 Development, Drift Tubes - RF and Beam Geometry. Comparison of A-12 to A-24
The final r.f. characteristics of A-12 are shown. The mechanical features are available in UCRL-1859. If A-12 were to be changed to 24.2 mm rather than 12.1 mm, keeping the same length and the same constant average coil gradient of 0.375 MV/ft., the characteristics of such an A-24 can be obtained from the attached curves.
