Remote Control (RC) Plane’s Designing, Building and flying Report!

Introduction: This reports comprises all the efforts put into by the first ever team , named MUET HAWKS, from Mehran University Of Engineering and Technology (Jamshoro, Sindh) , rated in top ten engineering universities in HEC ranking, to design ACE 999 that will be competitive in 2013-14 DBFC/AIAA GIKI. The aim of the whole design process was to get maximum score in the Competition and bring home the victory. To do so we had to be successful in two flight missions and in getting maximum score in project design report. Competition score is determined by keeping various parameters under observations.

1.2) Design summary: In order to make different design from previous DBFC competition designs Team MUET HAWKS decided to select POD and BOOM  RC- Plane and after selecting this design

They tried to represent this design more optimistically and efficient than all other Pod and Boom type RC plane. Team’s motive doesn’t only depend on the design but also in the aircraft performance. The advantage of using such models is it needs light weight and because of which they are more effective in the flight performance.  At the back of the pod,a powerful DC motor is mounted. Best results in competition missions were achieved by use of high lift airfoil in wings and light weight fuselage.

Performance: Predicted air craft performance for both missions is as follows. The air craft lifts up within 40 ft. of run way distance and completes 6 laps in 6 minutes and 0 seconds with the wing loading of 22 g/sq.dm. The L/D ratio during Cruise for mission is 13 and the gross take-off weight is 3 lbs. Take-off speed is expected to 13.5m./s with the plus minus 5 ft./s error due to tire friction. For mission two with internal payloads placed among fuselage hollow cube body. The air craft gains 10 m/s speed on run way and lifts up within 55 ft. of run way distance. in 4 mins and 1 sec almost 3 labs are completed. The wing loading for mission two is  57 g/sq.dm with gross take-off weight of 7 lb having good L/D. The loading time for mission is around 10 seconds. Since we cannot change or charge battery during both missions. For both missions battery is Ni-MH weighs approx. 1.5 lb. The altitudes were , 48 in Mission 1 and 39ft in Mission 2.
