Fundamentals of lift and drag , Other Engineering

Assignment Help:
  • Lift and drag are merely the resolved components in specific directions of a resultant aerodynamic force caused by the relative velocity V of the vehicle through the air.
  • If all one were concerned with was the rigid-body motion of the aircraft, then the pressure and shear-stress distributions caused by the flow could be entirely represented by a single force acting at the centre of pressure (CP). 
  • The CP is not a fixed point; it shifts with AoA, flow condition, and other variables. 
  • The force of lift is, by definition, perpendicular to V. 
  • The drag of lift is, by definition, parallel to V. 
  • We shall assume that the thrust generated by the engines acts parallel to V. 
  • For performance analysis, moments will often be in balance and one can treat all the forces as though they acted at the centre of gravity (CG).
