Book excerpt: A twin-barrel injection carburetor and a supercharger inlet elbow, forming part of the induction system of an aircraft engine, were used in a laboratory investigation to establish quantitatively the relation between wet- and dry-bulb temperatures of the de-icing air and the time required to recover a given air-flow loss due to icing. Tests were run at one severe icing condition during simulated operation at normal rated power and at two severe icing conditions at 60-percent normal rated power. The air-flow recovery times were determined for dry and humidified de-icing air at various temperatures from 40 to 120 degrees F.

Book excerpt: The carburetor and engine-stage supercharger assembly of a fighter aircraft were laboratory-tested to determine the icing characteristics of the induction system under three simulated engine power conditions with varying carburetor-air temperature, relative humidity, simulated-rain injection, rain and fuel temperature, fuel-air ratio, and fuel of different distillation characteristics. All runs were of 15-minute duration, after which the carburetor and supercharger inlet elbow were visually inspected for ice formations. The limits of visible icing and serious icing, which is defined by a 2-percent reduction in air flow in a 15-minute test period, were found to form at progressively lower air temperatures and heat contents as engine power was increased. Relatively small accumulations of ice on the throttle plates caused more serious reductions of ice on the throttle plates caused more serious reductions in air flow than large deposits of ice in the supercharger inlet elbow. Turbulences below the throttles and circulation of fuel in the inlet elbow ere responsible for severe cooling of the throttles and heavy deposits of ice on the under surfaces owing to the refrigeration effect of the fuel evaporation. This effect was less noticeable as throttle angle and air flow were increased for high power conditions.

Book excerpt: On order to eliminate the formation of ice on the carburetor throttle plates of an aircraft-engine induction system, two modifications of the throttle design and a variation in the method of throttle operation of the twin-barrel injection carburetor were tested.

This book was released on 1945 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laboratory research apparatus and testing technique developed and used at the NACA Cleveland laboratory to investigate the icing and de-icing of the carburetor and supercharger inlet of typical aircraft-engine induction systems under conditions closely simulating flight through a wide range of engine icing conditions is described. The apparatus permits the installation of the carburetor and accessory housing including the inlet elbow and the supercharger assembly, which is driven by an electric dynamometer. A representative setup is shown.

Book excerpt: Tests were conducted to determine the effects of internal coolants injected with the fuel on the icing characteristics of a twin-barrel injection carburetor mounted on an engine-stage supercharger assembly. Tests were made at air-flow conditions that simulated war emergency power.

Book excerpt: In order to prevent the formation of refrigeration icing in the induction system of an aircraft engine, several modifications to the spray nozzle were designed and tested. The modifications varied from a revised pintle to actual changes in the point of fuel injection without a basic alteration of the standard spray nozzle. Prevention of refrigeration icing in the carburetor and inlet elbow was achieved when the fuel spray was completely removed from the inlet-elbow passage and injected directly into the supercharger inlet through orifices in or attached to the rotating impeller. Two fuel-injection systems, a spinner type and a drilled-inducer type, that satisfactorily prevent the formation of refrigeration icing in the induction system were developed.

Book excerpt: Flight tests were conducted on a twin-engine fighter airplane at pressure altitudes up to 10,000 feet with simulated conditions of moderate, heavy, and excessive rain to determine the increase in enthalpy of the charge air due to the turbosupercharger, to determine the rate of enthalpy increase of the charge air resulting from a sudden increase of engine power, and to compare the conditions that caused induction-system icing in flight with those that resulted in icing of the same carburetor and supercharger inlet elbow in laboratory tests.
