Project Name : Convertible Airfoil
Theme Name : Transports & Communication
Aim: To provide a solution to the problems that arise during disasters.
Objective: To reduce the space required for take-off by increasing the lift, thereby making the aircrafts viable to reach the disaster affected areas.
Scientific Principle: A thicker airfoil (conventional airfoil) generates more lift but also has drag as penalty. A stepped airfoil traps a vortex at rear end generating greater lift but vortex is blown off at high speed.
Convertible airfoil employs a system of integrated flaps to convert a stepped airfoil to a conventional airfoil during flight allowing independent high lift and high speed profiles with greater efficiency.
Materials Used/Procedure:
Corrugated Plastic for Wingspan and Chord Length, Wooden Dowels, Carbon Fibre, Epoxy and Industrial Strength CA, Wooden Ribs, Servo Motors, Connection Wires
Working/Investigation/Findings:
Hybrid between conventional and KFM airfoil.
Provides best of both configurations, decreases flight time (wing air travel)
Greatly increases lift and air penetration.
Provides opportunity to take off on small air strips.
Utility and Further Scope of the Project:
Disaster Management: reduces space required for takeoff by increasing the lift generated making it possible for planes to help those in needs.
Fuel Efficiency: easily switches between high lift and high speed profiles, reducing flight time and increasing efficiency.
Generating Employment: construction of airfields and air strips in villages and remote areas, providing avenues for employment in these regions.
Greater Pay Load Capacity: flexible range of centre of gravity and high lift allows the planes to support much greater payload as compared to conventional air craft, thus increasin efficiency of transport of large load via air.
Name of the School: Chirec Public School, Hyderabad.
