WitrynaFurther analysis found that the turbine nacelle motion increased with increasing significant wave height and was also significantly influenced by peak wave period. … Witryna10 maj 2024 · The motions are: pitch and surge in line with the wave direction; yaw, sway and roll transverse to it; and heave vertically. The acceleration at the nacelle should be less than 0.3 g to avoid damage to the power electronics when operational (DNVGL 2024). This is partly caused by platform pitch which should also be minimised to …

WitrynaOn most single-engine aircraft, the engine and nacelle are at the forward end of the fuselage. On multiengine aircraft, engine nacelles are built into the wings or attached to the fuselage at the empennage (tail section). Occasionally, a multiengine aircraft is designed with a nacelle in line with the fuselage aft of the passenger compartment.
