Tricopter -design and its fabrication

  1. 1. Design and Fabrication of TRICOPTOR By C.HARTHICK 8790189041
  2. 2. Introduction
  3. 3. Project Overview • Mission and motivation • What is Tricoptor • Tricoptor flight dynamics • Modeling of Tricoptor • Major components • Challenges we faced • Summary of Components • Application and uses • Further implementations • Testing • conclusion
  4. 4. Our mission and motivation • Building with less budget • less cost-high efficiency • Reducing over all weight along With frame and miscellaneous • DARPA and DARO
  5. 5. WHAT IS TRICOPTOR * It’s an aircraft similar to a helicopter except it has three rotor . * The beauty of the design is that it derives lift and propulsion from three sets of horizontally revolving rotors. * Four helicopter gyros makes the tricopter super stable
  6. 6. We rely on a solid foundation of the following to allow us to understand the flight of these machines:- 1. Newtonian Mechanics 2. Bernoulli’ Principle. Trirotor Dynamics: pitch = Elevator Roll = Aileron Yaw = Rudder Flight Dynamics
  7. 7. Design using coral software Modeling
  8. 8. Controller/stabilizer board IC: Atmega168PA Gyro: Murata Piezo Input Voltage: 3.3-5.5V Signal from Receiver: 1520us (4 channels) Signal to ESC: 1520us Brushless dc motor Kv(rpm/v):1800 Volts:7.4~11.1v Weight:50g Poles:12/14 Max.pull:840gms Max.power:310watts Major components
  9. 9. Electronic speed controllers propellers Frame made with glassy proxy sheet Li-Po battery Major components
  10. 10. RC TRANSMITTER/RECEIVER Transmitter / Receiver: 2.4GHz Channels: 6channels Model type: Heli, Airplane, Glider RF power: less than 20db/0.8W Modulation : Frequency Modulation Code Type :PPM/GFSK Power: 12V DC Weight:680g Low voltage warning: LED warning Throttle cut Computer Programmable USB Socket Major components
  11. 11. Real Time Components
  12. 12. » Scarcity of components » Designing of over all frame with less weight » Hover and Balance functionality » Combining both the gyro and accelerometer values » Financial restrictions » Safety concerns Challengeswe faced
  13. 13. Summary of components Controller board : kk multicoptor board Propellers : 3 Brushless dc motors : 3 ESC : 3 Li-Po battery : 1 Aluminum channel : 4mts Rod Glassy proxy sheet : 2mm G-locks : 1pak Gold connectors : 9 Screws and nuts : 1,1/2,1/4,3/4 inches Radio channel : transmitter and receiver Weight : 1.8kgs Flight time : 7 Minutes Distance : 1 Sq km
  14. 14. APPLICATIONS AND USES •Military purposes for spying •Aerial surveillance •Rescue purpose •Industrial and commercial purposes •Temperature and pressure measurement •Wireless communications among other UAV’s •For target tracking •For film shootings
  15. 15. Further implementation >> Additional IR sensors, cameras and wireless technologies like GSM can be added to make the UAV more useful. >> A camera can be mounted on this UAV since it has a payload capacity of 0.5 kg in tri- rotor mode. >> GPS for auto landing at the origin
  16. 16. Testing STAGE 1 : Mechanical design with perfect ‘CG’ STAGE 2 : Propellers selection and its rotation STAGE 3 : Electronic connections/wiring STAGE 4 : Balancing the tricoptor(major stage of entire project) STAGE 5 : Controlling the transmitter at its best STAGE 6 : Programming both stabilizer board and transmitter STAGE 7 : Gyros setup for kkboard v5.5 STAGE 8 : Vertical takeoff and Landing(VTOL)
  17. 17. Final output
  18. 18. conclusion The capabilities of this design may prove to be asymptotic in nature, however these may not be realized until proper funding is given and experimental analysis is conducted. Given the stable platform produced by this group, further research and development can and should be done to improve the functionality of our design. This project has increased our interests in robotics and autonomous design, knowledge which will serve useful throughout our professional careers. We feel that this form of thinking and engineering will be prevalent in the modern world and beyond as new applications are found which will test the limits of current technologies.
