Solution Manual For Aerodynamics For Engineers 6th Edition Bertin Cummings

How is the stall speed changed by a steeper bank angle? {Ans: Increases}What causes P-Factor? {Ans: Ascending and descending blades producing different amounts of thrust based on different AOAs of the blades}What is the greatest contributor to lateral static stability? {Ans: Wing dihedral}Stability vs Maneuverability {Ans: Increased stability = Decreased maneuverability Increased maneuverability = Decreased stability}Erect accelerated spin {Ans: Control stick other than full aft}Total Energy {Ans: TE = PE + KE}What is propeller torque? {Ans: Aircraft ROLLS opposite the propeller rotation}Conservation of Angular Momentum {Ans: - Lower pitch results in higher rotation rate - Higher rotation rate results in larger nose down movement}What effect does a change in configuration have on TA and TR? {Ans: - No effect on TA - TR is increased (Gear down)}Lower the energy (airspeed) at stall entry means {Ans: Less the post stall gyration tendency}What is propeller efficiency? {Ans: - Ability to convert engine output into thrust - Never 100% due to gearbox friction propeller drag PE = THP/SHP THP is less than SHP}What is the function of leading edge slats? {Ans: Controls boundary layer separation}Density {Ans: Density = Mass/Volume Mass
