Cruise Control

By Aeromodelling Club

Problem Statement:
Design and make a wireless remote controlled aircraft (using electric motors only), which has all three degrees of freedom including yaw, pitch and roll and that can complete a specified path.

Rules and Regulations:

• RC Plane Designing

  • Model Specifications:
    • An aircraft is defined as an object that has the four forces of flight, namely lift, drag, weight (gravity) and thrust due to propeller acting on it at any point of time.
    • The Aeromodel should have a wing span of at least 80 cms.
    • The aeromodel must be hand-made. For information on design you are advised to visit http://students.iitk.ac.in/aeromodelling.
    • A team can use only one model throughout the competition. The same model should be used in all the rounds. In case of any damage, small modifications are allowed.
    • The use of IC engines is prohibited. Only electrical motors are allowed.
    • The potential difference, between any two points on the machine, must be lower than or equal to 12V (recommended voltages 7.2V, 7.4V, 8.4V, 9.6V, 11.4V or 12V) at any point of time during the competition.
    • The participants are free to use the materials of their choice. However the use of Balsa wood or foam (sun board) or sun pack is advisable. Foam is light, easy to handle and fabricate the aircraft making it the best choice.
    • Participants can use Design-Foil software to design the aircraft wing.
    • Participants must make all parts of the aircraft themselves. Usage of Ready-to-Fly (RTF) and Almost-Ready-to-Fly (ARF) kits is strictly prohibited. Use of readymade actuators/motors, remote controls and propellers is allowed.
    • Use of gyroscopes (gyros) is prohibited.
    • If anyone found not following above rules will be disqualified.
  
  
  • Judging Criteria:
    • Designing of an aircraft is a very important part of this competition. The tasks in competition include aerobatics, sharp turns and speed. So your aircraft should be such that it can perform the given tasks effectively.
      The tasks for the competition are:
      1. Aerobatics (manoeuvring).
      2. Safe landing.
      3. Flying as fast as you can in addition to taking sharp turns to complete the run in minimum possible time.
      Each entry will be judged before the start of the task. The judging will be based on the following criteria:
      1. Functionality of Design.
      2. Innovation of Design.

• RC Flying

  • Round 1: Power and Endurance
    • A maximum propulsion time of 1 minute (including take off) is given to the participant after which participants have to cut off the power and glide their plane to maximize its time of flight.
    • Points: T(Gliding Time, in seconds) + L(Landing, maximum 25)
  
  
  • Round 2: Manuevers
    • In a given time of 5 minutes (including takeoff and landing), the aeromodel will have to complete maximum number of laps between two given checkpoints 250 metres apart.
    • Points: [N(Number of laps) * 20] + L(Landing, maximum 25)

Team Specifications:

• Each pool should come up with a maximum of 1 RC plane.

Scoring:

RC Plane Design:	100 points
RC Flying (Round 1):	T + L points
RC Flying (Round 2):	(20 * N) + L points

Note: In case of any disputes, the decision of the organizers would be final and binding to all.
