  1. Mini Autonomous Flying Vehicle • CASDE is part of the National effort to develop a Micro Air Vehicle. • CASDE has chosen a Mini Vehicle, in the short term, keeping in mind the autonomous mission. • CASDE feels that ~500 Gms. of Avionics is bare minimum to make a mission autonomous. • A 2 Kg. Aircraft, with 500-600 Gms. payload, needs to be demonstrated.

  2. Mini Flying Vehicle Scenario

  3. CASDE’s Approach • Instrumented Flying Platform • Aircraft Fabrication and Instrumentation • Correlation of Mission with Flight data • Videography Platform, Solar Powered Aircraft • SE Approach to Design & Development • Mission Realization • Avionics Development & Integration Studies • Autonomous Mission Implementation

  4. Instrumented Flying Platform Parameters: Nx Ny Nz q h v e  Span - 1.7 m Chord - 29.5 cm Fuselage length - 1.07 m Weight - 3800 gm (fuel) Weight of Inst. - 500 gm Engine Disp. - 7.5 cc Power - 1.6 BHP

  5. Instrumented Flying Platform Recorded Flight Data for a Loop

  6. Videography Platform Target Launch • Design & Build an Aerial Vehicle Capable of Carrying a Video Camera/ Transmitter. • A circle & Two Rectangles as Targets for Videography • Maximum Dimension 24” & All-Up-Weight Less Than 1 kg. Distance 500m • Wing Airfoil - Selig 3021 - 095 -84 • Wing Span - 24” (both wings) • Wing Chord - 6” • Wing Gap - 4.25” • Wing Area - 288 sq. in (2 sq. ft) • Fuselage - 23.5” • Tail span - 14” • Tail Chord - 4.5” • Tail Arm - 12.25” • Max AUW - 860 gm (30.27 oz) • Wing loading - 15.14 oz/sq. ft

  7. Videography Platform

  8. Solar Powered Aircraft Span : 90 cm Aspect ratio : 8 Power requirement : 4 watts Solar Panel weight : 70 grams Total weight : 140 grams

  9. Avionics Development & Integration • Components off the Shelf • Selection and Integration • Weight, Size & Performance as Criterion

  10. CASDE MAV Configuration • Fixed Wing with Speed of 10-35 Metres/Sec. • Avionics Payload of ~ 500-700 Grams • Autonomous Flight Capability • Way Point (with Mission) Based Navigation • Range of ~ 5 km & Endurance of 30 Minutes • Video Surveillance & Live Transmission • Stabilized Platform for Good Picture Quality

  11. CASDE MAV Development Strategy • Aircraft • SARIKA-II of IISc OR • Instrumented Flying Aircraft of CASDE • Navigation, Guidance and Control Strategy • NGC Developed by ADE for Nishant to be used • Avionics • Package to be Developed by CASDE • Simulations • Ground Based Off-line, OILS, AILS & Mission
