  • blade stall — As it refers to rotorcraft, it is the condition of the retreating rotor blade when in forward flight and when operating at an angle of attack greater than the maximum angle of lift. This occurs at high forward speeds and when settling with power …   Aviation dictionary

  • Retreating blade stall — is a hazardous flight condition in helicopters and other rotary wing aircraft, where the rotor blade rotating away from the direction of flight stalls. The stall is due to low relative airspeed and/or excessive angle of attack (or AOA).… …   Wikipedia

  • retreating-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 …   Aviation dictionary

  • Stall (flight) — For other uses, see stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is… …   Wikipedia

  • retreating 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 …   Aviation dictionary

  • Compressor stall — A compressor stall is a situation of abnormal airflow resulting from a stall of the aerofoils within the compressor of a jet engine. Stall is found in dynamic compressors, particularly axial compressors, as used in jet engines and turbochargers… …   Wikipedia

  • Dynamic stall — is a non linear unsteady aerodynamic effect that occurs when aerofoils rapidly change the angle of attack. The rapid change can cause a strong vortex to be shed from the leading edge of the aerofoil, and travel backwards above the wing. The… …   Wikipedia

  • compressor stall — A condition in which the compressor blades stall as the relative airflow meets the blades beyond the critical angle. This can happen at start up, during rapid acceleration from low RPM, or during a sudden reduction of mass airflow, when a few or… …   Aviation dictionary

  • Dissymmetry of lift — in rotorcraft aerodynamics refers to an uneven amount of lift on opposite sides of the rotor disc. It is a phenomenon that affects single rotor helicopters in lateral flight, whether the direction of flight be forwards, sideways or in reverse.… …   Wikipedia

  • Helicopter — For other uses, see Helicopter (disambiguation). Helicopter An LAPD Bell 206 …   Wikipedia
