Gas turbine (jet) engines used in helicopters do not produce thrust. Instead, the air exiting the engine passes over a wheel (normally called the power turbine) with specially designed blades that turn a shaft. The shaft is geared down and connected to the transmission that drives the main rotor system. This design is called a turboshaft engine and its power is measured in shaft horsepower (shp). As in typical turbine engines, some of a turboshaft’s power is used to drive the inlet compressor or gas producer section.
The tail rotor on Eurocopter’s AS350 AStar helicopter uses weights to generate a Centrifugal force to help balance the forces that exist when changing the blades’ pitch angle. Known as boss weights, exactly how they work is sometimes misunderstood.

Mumbai: The wait for travelling in an amphibious aircraft that can land on runways or in water bodies during the course of a single journey is all set to get longer. The Maharashtra Tourism Department Corporation’s (MTDC) plan to begin the seaplane services in April has hit a major roadblock as the ministry of defence (MoD) is apparently going slow in issuing a No-Objection Certificate (NOC) for the project. Sources said the MoD is studying the proposal minutely in view of security reasons and has sought answers to its various queries from M/S Mehair Ltd, the operator of the project. A defence spokesperson said, “The NoC application is under process.”
