Report on Production Test No. 313-68-M: Recanning of warped slugs segregated after the centrifuge by technical warp gauge

Description: It has been found that warped slugs which produce ``non-seats`` segregated after the centrifuging operation by use of a suitable gauge. The slugs which do not pass the gauge are quenched in water and set aside for later recovery. The purpose of this test was to determine if the rejected slugs could be straightened, degreased and recanned by dipping them directly in the bronze and then through the subsequent steps. One hundred and twenty-nine slugs rejected by the warp gauge were straightened, d… more

TO₃ Reduction and Chlorination in the Experimental Glass Fluidizer

Description: Abstract: "Temperatures above 400 C are required before reduction will take place with AH3. Above 500 C, a pyrophoric product was obtained. The chlorination temperature should be about 350 C initially and above 450 C at the end of the reaction to achieve 99% chlorination."

The Effect of Modified Baffles and Auxiliary-Cooling Ducts on the Cooling of a Double-Row Radial Engine

Description: Report discussing testing to determine the cooling effect of modified baffles and auxiliary-cooling ducts on the rear-row cylinders of a double-row radial engine. The modified baffles were found to reduce the temperatures of the exhaust-valve seats, but did not have an effect on the valve-guide temperatures. The auxiliary-cooling ducts reduced temperatures of the exhaust-valve seats and rear spark plug gaskets.

Estimation of F-3 and F-4 knock-limited performance ratings for ternary and quaternary blends containing triptane or other high-antiknock aviation-fuel blending agents

Description: Charts are presented that permit the estimation of F-3 and F-4 knock-limited performance ratings for certain ternary and quaternary fuel blends. Ratings for various ternary and quaternary blends estimated from these charts compare favorably with experimental F-3 and F-4 ratings. Because of the unusual behavior of some of the aromatic blends in the F-3 engine, the charts for aromatic-paraffinic blends are probably less accurate than the charts for purely paraffinic blends.

Analysis and modification of theory for impact of seaplanes on water

Description: From Summary: "An analysis of available theory on seaplane impact and a proposed modification thereto are presented. In previous methods the overall momentum of the float and virtual mass has been assumed to remain constant during the impact but the present analysis shows that this assumption is rigorously correct only when the resultant velocity of the float is normal to the keel."

Suitability of 18 Aromatic Amines for Overwater Storage When Blended With Aviation Gasoline

Description: Report discussing testing of aromatic amines as antiknock additives, and more specifically the suitability of overwater storage for these fuel blends. 12 aromatic amines of three different concentrations at two temperatures were measured. The chemical properties of the most promising fuel blends are described in more detail and correlations were noted.

Cooling of Gas Turbines, 2, Effectiveness of Rim Cooling of Blades

Description: An analysis of rim cooling, which cools the blade by condition alone, was conducted. Gas temperatures ranged from 1300 degrees to 1900 degrees F and rim temperatures from 0 degrees to 1000 degrees F below gas temperatures. Results show that gas temperature increases up to 200 degrees F are permissible provided that the blades are cooled by 400 degrees to 500 degrees F below the gas temperature. Relatively small amounts of blade cooling, at constant gas temperature, give large increases in blade… more

The Effect of Impurities Upon Sulfide Refractories

Description: Abstract. A summary of the effect of metal, carbon, silicon, and oxygen impurities upon the various sulfide refractories is given and the proper procedures for elimination of the impurities are discussed. CeS which is properly prepared can be handled in air without danger of catching fire or appreciable oxidation. 650 satisfactory crucibles have been made to date using sulfides which were screened and pressed in air with less than 0.5% oxygen pickup. The other cerium and thorium sulfides ar… more
