Flight - X

By Aeromodelling Club

Problem Statement:
Design a free flight glider capable of flying by its own once launched. It should remain airborne for maximum timeand cover a maximum horizontal distance. It should be capable of performing a few basic manoeuvres.

Arena:

• Participants would have to hand launch their aircraft from a pre specified launching zone.
• You can launch your aircraft in any direction.
• The launching zone would be platform of approximately 2 meters in height.

Rules and Regulations:

• The glider should have a maximum wingspan of 50 cms.
• There is no weight limit.
• You can use any material of your choice, though we would prefer Balsa wood.
• You can use any launching method.
• Use of launching mechanisms is allowed, provided it should only provide initial thrust. After launching, it should fly on its own.
• You can use any aerofoil of your choice.
• Use of any electronics on the aircraft is strictly prohibited.
• You can do any on the spot changes on your aircraft provided it lies within the provided specifications.
• If your aircraft breaks at any point of the competition, you will be eliminated from that particular round, and the team will be awarded points it scored just before breaking. Hovewer, you are still eligible for the nextround after repairing your aircraft making a new one.
• There is no negative point at any point of the competition.
• If any team is found not following above rules will be disqualified immidiately.

Team Specifications:

• A team must consist of minimum 3 members.

Procedure and Scoring:

There will be 3 rounds:

• Qualification Round
  • In this round the participants have to show their design to the judges and explain their design. After that theparticipants have to hand launch their aircraft to make it glide freely, to show it has got flight capability. It shouldhave a decent flight.
  • There are no points for this round.
  • The launching mechanism is not allowed only at this round.
  • If you don’t qualify this round, you are still eligible for next rounds, but you will be given last slot.
• Free-Flight Round
  • You have to fly your aircraft for maximum range and flight time.
  • You will be given two-two chances for each part, best of two will be entertained.
    1. You have to launch your aircraft for maximum horizontal range.
    2. You have to launch your aircraft for maximum flight time.
  • Points:
    • R = Range (Horizontal displacement between launch point and landing point, in meters)
    • T = Time of flight (Total time your aircraft is airborne, in seconds)
• Manoeuvres
  • You have to perform some basic manoeuvres by your aircraft. Some of them are listed below:
    • Vertical Loop
    • Horizontal Loop
    • You can also perform any other manoeuvres of your choice, on which extra points will be given.
  • Points:
    • V = Points for vertical loop (out of 10)
    • H = Points for horizontal loop (out of 10)
    • E = Points for extra manoeuvres you perform, if any(out of 10)*
    • * if you perform only above two manoeuvres, E=0 points.
• Total Points: R + T + V + H + E

In case of tie, the judges can ask the teams to perform any task on the spot which will decide the winner.

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