31Swashplate (helicopter) — This article is about the swashplate in helicopters, see also the swashplate article which describes all uses of the mechanism. A swashplate is a device that translates the pilot s (or autopilot s) commands via the helicopter flight controls into …
32Backpack helicopter — A backpack helicopter is a helicopter motor and rotor and controls assembly that can be strapped to a person s back, so that he can walk about on the ground wearing it, and can use it to fly. Its harness, like a parachute harness, should have a… …
33advancing blade — In a translational flight, the rotor blade moving forward into the relative airflow (i.e., it is moving in the same direction as the helicopter). Each blade advances through 180° of its travel, normally from dead astern to dead ahead. In the case …
34main rotor — noun rotor consisting of large rotating airfoils on a single rotor helicopter that produce the lift to support the helicopter in the air • Hypernyms: ↑rotor • Part Meronyms: ↑rotor blade, ↑rotary wing, ↑rotor head, ↑rotor shaft …
35Single-blade propeller — A single blade propeller is a notable configuration of a propulsion system used on aerodynes to generate thrust. Normally propellers are multiblades. The simplicity of a single blade propeller fits very well on motorized gliders, because it… …
36retreating-blade stall — The stall of a helicopter rotor disc that occurs starting at the tip of the retreating blade. This happens when the helicopter forward speed is high. The individual angle of attack of the retreating blade becomes larger because the downward blade …
37retreating blade — The process of the rotor blade moving away from the relative airflow (i.e., in the direction opposite to which the helicopter is flying). See retreating blade stall …
38E-Flite Blade CX and CX2 — The E Flite Blade CX is an entry level, ready to fly electric micro R/C helicopter designed and distributed by E Flite, a division of Horizon Hobby of Champaign, Illinois, USA.Blade CXThis model was introduced in late 2005 as an easier to fly… …
39T-Rex (RC helicopter) — The T Rex is an electric powered radio controlled helicopter model produced by Align. Since the initial release of the helicopter several years ago, Align has produced several variants of its T Rex 450 and T Rex 600 models. T Rex 450 The T Rex… …
40dissymmetry of rotor thrust — A condition in which one side of a rotor disc produces more thrust than the other. The speed of relative airflow over the advancing blade is higher than that of the retreating blade. The rotor thrust of the advancing blade also is higher than… …
