negative thrust propeller
1Thrust reversal — Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine s exhaust or changing of propeller pitch so that the thrust produced is directed forward, rather than aft. This acts against the forward travel of the… …
2Propeller — A propeller is essentially a type of fan which transmits power by converting rotational motion into thrust for propulsion of a vehicle such as an aircraft, ship, or submarine through a mass such as water or air, by rotating two or more twisted… …
3Ducted propeller — Kort nozzle A ducted propeller is a propeller fitted with a non rotating nozzle. It is used to improve the efficiency of the propeller and are especially used on heavily loaded propellers or propellers with limited diameter. It was developed by… …
4Controllable pitch propeller — A controllable pitch propeller (CPP) or variable pitch propeller is a type of propeller with blades that can be rotated around their long axis to change their pitch. If the pitch can be set to negative values, the reversible propeller can also… …
5reverse/reversible thrust — The thrust from a power plant that can be reversed in direction to act as a brake. In reciprocating engines and turboprop aircraft, a propeller is given a negative pitch setting, or a reverse pitch. In gas turbine engines, devices are used to… …
6Jet engine — For a general overview of aircraft engines, see Aircraft engine. A Pratt Whitney F100 turbofan engine for the …
7Turboprop — A turboprop engine is a type of aircraft powerplant that uses a gas turbine engine to drive a propeller. The gas turbine is designed specifically for this application, with almost all of its output being used to drive the propeller. The engine s… …
8Critical engine — The critical engine of a multi engine, fixed wing aircraft is the one whose failure would result in the most adverse effects on the aircraft s handling and performance. Contents 1 Description 2 Factors affecting engine criticality 2.1… …
9harbours and sea works — Introduction harbour also spelled harbor any part of a body of water and the manmade structures surrounding it that sufficiently shelters a vessel from wind, waves, and currents, enabling safe anchorage or the discharge and loading of… …
10airplane — /air playn /, n. 1. a heavier than air aircraft kept aloft by the upward thrust exerted by the passing air on its fixed wings and driven by propellers, jet propulsion, etc. 2. any similar heavier than air aircraft, as a glider or helicopter. Also …
