OPTIMUM INSTALLATION OF A COMMON RAIL DIESEL ENGINE ON A “CLASSICAL” HELICOPTER: THE UH1

Abstract: A feasibility study for the installation of a CRDID (Common Rail Diesel Engine) on a medium helicopter is introduced. The total mass available for the CRDID is evaluated starting from fuel consumption and helicopter data. A derivative of an automotive engine was considered. The installation of the new CRDID was then studied. The result was the evaluation of the power plant installation mass that proved to be lower than the maximum admissible. The installation is then possible. Care should be taken in the cooling system to avoid large penalties in power and efficiency. For CRDID powered helicopters, the ejector exhaust system can be successfully used. With CRDIDs, huge advantages can be obtained on operating costs due to reduced fuel consumption, safety and helicopter availability. In fact, diesel fuel is available everywhere and flights to airports just for refueling can be avoided. |
