Rc Plane free essay sample

Remote Controlled Mini Air Vehicle Design, Build and Fly What is a MAV 1. MAV is basically a much smaller prototype of an actual aircraft and hence its dynamics are much different and tougher to understand. 2. There are 3 degrees of freedom for a MAV: roll, pitch and yaw. 3. To achieve these motions, there are three control surfaces: ailerons, elevators and rudder. CONTROL SURFACES Forces on a MAV Realize the problem statement Decide the dimensions of the MAV Select the components according to the problem statement and the weight of the MAV Get it flown by some one who knows flying. Integrate all the parts with best possible precision and test the motors. Steps to make a MAV Choose Material for body : 1. Balsa? Soft and light Easy to work on Available in strips Most widely used in aero modeling 2. Thermocole / Foam? Choose High Density Thermocole (HDT), Foam Very light Needs Reinforcement Source: 1.

LiPo battery: 600 Rs. 6. Propellers: 95Rs. Each Total cost involved (without the RC system and the propellers): Rs. 3175 Foam costs around 120Rs. Per sheet. Source: 1. Online but the costs will become 1. times due to shipping charges. 2. Mr. Sai from Chennai. (His son had won the last year’s Techfest’s powered glider event. ) Some IMORTANT Tips!!!! 1. Always start off with designing the MAV on paper and show it to a professor/senior before starting off with building. 2. Check the LiPo battery for its voltage before using it. You may need to charge it once. (We had almost a blast due to this. And worse we lost the 2000Rs. Worth battery. ) 3. MAV is a highly unstable plane in flight. Hence any slight asymmetry in the design will get highly demonstrated in the flight. . The design of MAV is more about precision than its actual design. Also try to keep its surface smooth to reduce drag. Try to give an aerofoil shape to the wing. 5. The building of the MAV should easily be done within 3 days after having all the components and the design ready. FLYING!!!! 1. The actual challenge is flying the RC plane which needs LOTS of directed practice. 2. Last year, we had our plane ready 10 days before the competition and tried our level best to fly it but couldn’t even fly till 10 mts. . This year, you have many facilities which can help you in learning flying. Facilities in the department: 1. We have imported a RC Flight Simulator which simulates the flight of a MAV and has the remote controller as the joystick. It will give the nearest? to? actual flying experience. 2. We have a RC gyroscope which autopilots one degree of freedom. I practiced it by auto piloting the roll motion and was very helpful in learning. (We didn’t have the RC Flight Sim at that time. )
