MATERIALS
Procured depron
Fuselage construction
Wing construction
The Ribs
• Fuselage
• Former: Providing the main structure
• Skin: As per monocoque, it gives rigidity and shell.
• Housing most electronics.
• Belly reinforced with Fiber Tape.
• Power Pod
• Containing the ESC and Motor Mounted over the
Firewall.
• Slides along the slots created in the BulkHead and
formers.
CONSTRUCTION
• Twin Boom
• 3mm Carbon Rods; Structure Of Booms
• Inverted V-Tail
• Containing the Elevons, contoured to
form spear at joining base.
• Hinged Control surfaces actuated by 9g
servos.
• Push Rod- Control Horn Linkage.
CONSTRUCTION
Semi Monocoque
fuselage and wings.
CONSTRUCTION
• Wing (Port and Star Board Side)
• Airfoils, placed along the span aligned with the chord;
For Lateral Stability.
• Carbon Fiber Rod intersecting the chord-wise airfoil;
For Longitudinal Stability
• This gives strength to the entire wing base and the
rods take the bending moments generated through
out the flight.
• Two spars enable locking against any torsional
moment at the chord alignment of wing and fuselage.
• Ailerons cut out and actuated by 9g metal gear servos.
ELECTRONIC CIRCUIT
Mission Plan & Flight Log
• Containing the flight plan along with the maneuvers.
• Payload drop paradigm.
• Flight Log: such as date, time and conditions of flight
• Duration
• Weather
• Performance and Observations

Application
Our UAV should successfully be able to perform:
• Search and Rescue Operations.
• Expendable.
• Monitoring ( Wildlife Sanctuaries, City Wide Mapping, etc).
• Providing platform for surveillance companies to perform beta
tests of their cameras and sensors.
• Relief Package Drops.
• Agricultural Inspection.
• Advance to Combat Drone.
Conclusion
At the end of this undertaking, we expect to:
Have created and tested a working model of the above outlined UAV
Experimentally justify the software generated theoretical data
