Introduction To Aircraft Design

Introduction Wing Loading and Thrust Loading Basic Design - Lift and Drag, Range and Endurance, Mission Requirements. Range and Endurance: Propeller-driven Aircraft, Fuel Consumption: Cruise Flight, L/D for Maximum Range and Endurance, Range and endurance for Jet-driven Aircraft, Estimation of Fuel for a Mission. Design Considerations: Power Plant, Gross Weight. Design Considerations: Airfoil Selection.

• Design Considerations Wing. Wing Design: Air foil. Wing Design: t/c, Camber and Leading-Edge Radius.
• Wing Design Aspect Ratio. Wing Design: Sweep, Twist and Taper Ratio, Wing Arrangements, Tail Arrangements, Aircraft Structure, Wing Loading and Power Loading, Thrust Loading and Wing Loading. Thrust Loading, Wing Loading. Wing Loading: Maneuver, Climb and glide. Take-off: Wing Loading and Thrust Loading, Take-off and landing distance, Stall and High Life Devices.

Wing Loading Take-off and Landing, Revision (Wing Loading and Thrust Loading).Wing Loading: Designers Approach. Wing Loading: Designers Approach, Stability Considerations, Static Stability Basics, Wing and tail contribution to Longitudinal Static Stability, Conceptual Design,and Conceptual design Elevator Effectiveness, Elevator Effectiveness, Pitching moment, Elevator Effectiveness, Aircraft Maintenance Guidelines, Inspection for Aircraft, Weight fraction.

Introduction to Wind Tunnel Low speed wind tunnels, main features of supersonic, transonic and hypersonic tunnels, shock tunnels, closed and open circuit tunnels, Design of contraction and diffuser and other components of wind tunnel. Instrumentation and calibration of test section, blockage effects and boundary layer corrections, correction to lift drag, moment coefficient due to wind tunnel wall interference.

Measuring devices in Test Section Pitot tube static tube, yaw probes, five-hole probe, hot wire anemometers. Flow visualization techniques oil flow and smock flow. Flow field pressure measurements, Schlieren, shadowgraph and interferometer technique, laser Doppler, hot wire PIV technique, Wind tunnel balances, mechanical and strain gauge balances and their design. Scale effects. Non - aeronautical use of wind tunnels.
