Another area of expertise which PBS INDIA specialises in, is the production of high-quality turboshaft engines. The turboshaft engine operates on a similar principle as the turboprop engine and belongs to the category of engines which are most often used to power helicopters and hovercraft. One of their advantages is their ability to take off and land vertically; therefore, their use is invaluable in areas where there are limited possibilities for landing and in particular for emergency rescue services.
