| Ray Carlton Tallahassee, FL | The NA F-82H was the state of the art air defense fighter of that time, 1949-53. Made cold weather capable by major mods and add-ons, such as a larger radiator with an inlet air scoop exit air flap controlled by a thermostat and heater-blower motors to transfer the heated air from the radiator plenums to the de-icing channels in the wings, tailplane,cockpit heater control and defrosting vents, and the central gun bay to prevent ammo jams from cold temps.
It also incorporated an oil dilution regulator to dump a controlled amount of 100/130 octane gasoline into the oil sump, as per the ambient temperature. These fighters flew out of the cold regions and needed to be scramble ready. When the pilots and/or mechs were making them ready for the mission, and it was colder than a mad mother-in-law outside, then the oil was very thick and extremely viscous for passage through the oil pump and filtration system. The oil was momentarily diluted with fuel, in a controlled amount, to thin the oil for immediate passage through the pump and filter for a normal start up in very cold weather. Once the engine started and began the warm up to OT, the residual gas in the oil sump would evaporate out through the engine's crankcase vent. In all cold weather ops, piston engined aircraft had similar dilution systems while others utilized external heaters to blow hot air over the engines keeping the cowlings heated up and the oil normal. The H's were mostly used as day fighters and could maintain an operational altitude of 35K ft. where the expected Russian bombers would be flying. The H's were modified F's and G's which had the radar pod removed and winterized. The H's, like the F's and G's, also had the 2,300 HP Alisons spinning the wide blade AeroProducts 4-bladed prop to allow for bullet clearance from the centrally mounted 6 0.50 cals. The shorter,wider blade gave more thrust at T/O and was more efficient at altitude when the high blower was engaged and manifold pressure was at or above 40"Hg. No H's ever fired a shot in anger. They were soon replaced by all weather F-94B's. The first of the afterburning jets to enter service with the USAF. 07/16/2005 @ 01:06 [ref: 10770] |
