SUMMARY
This discussion focuses on calculating lift force in small aircraft using the lift equation and Bernoulli's principle. The lift force is defined by the equation Lift Force = Cl * ρ * A * V², where Cl is the lift coefficient (0.3), ρ is air density, A is wing area, and V is air speed. Participants clarify that the air speed V refers to the average speed over the wing surfaces. The relationship between pressure differences (P1 - P2) and lift is established, emphasizing that the lift force is generated by the pressure differential across the wing surfaces.
PREREQUISITES
