Problem Statement

Design Constraints

  1. The RC plane should measure a maximum of 1.0 m along any direction
  2. T/W =0.75 (if excess thrust is found, it will be neutralized by adding weight below the plane at center of gravity)
  3. The use of IC engines is prohibited. Only electrical motors are allowed
  4. The maximum voltage between any two points on the plane should be 12V at any point of time
  5. Use of gyroscopes (gyros) is prohibited
  6. One of the team members should fly the aircraft and another should call the stunts as they are performed (just before)
  7. No Design change will be allowed after the start of the competition

Round 1 : Free-Style

    Participants will be given 3 minutes for the Free-Style round. The point schedule is as follows:
    1) Horizontal circle
        a. Clockwise (10)
        b. Anti clockwise (10)

    2) Horizontal figure of 8 (15)
    The aircraft has to display a figure of 8 with its path in the horizontal plane in the minimum radius possible.
    The circles on either side have to be ensured to be of same diameter.

    3) Vertical circle (inside or outside loop) (20)
    A vertical circle (about the pitching axis) entered from straight and erect level flight.
    The aircraft can be straight or inverted at the beginning and end of the loop
    Problem Statement
    4) Vertical figure of 8 or Cuban eight (30)
    The aircraft has to display a figure of eight with its path in the vertical plane. In the maneuver the aircraft has to perform a roll after it starts descending from the highest position to ensure non inverted flight during the straight lines mentioned in the below figure.
    Problem Statement
    5) Hammer Head Maneuver or Stall turn (30)
    The aircraft has to pull up in the vertical direction and continue going upwards and has to make a 180 deg rotation about the yaw axis using rudder.
    Following this it has to come vertically down (nose-down) and turn into horizontal direction.
    Problem Statement
    6) Inverted flight for 5 seconds (25)
    7) Landing (35 points max)
    Each maneuver in the free-style round (except landing) has to be conducted atleast once. Participants can carry out maneuvers for more points after maneuvers 1 to 6 have been completed atleast once.

Round 2 : Arena Round

    The Arena consists of 4 vertical poles separated by a distance of 25 meters, 2 horizontal bars/gates at heights of 4 meters-”entry gate” and 4 meters - “exit gate” separated by a distance of 15 meters and a two gates with rectangular loops on the top (for better understanding of the arena- look into the arena diagram). Each gate would have enough space for planes to pass through, yet the skills of pilot could only guarantee a swift maneuver. The Arena will be at 30 meters from Take Off zone.

    The participants get the scoring as below :

    a A horizontal eight loop around the 2 vertical poles (P2 & P3) overshooting beyond P1 or P4 25 points per loop (none for incomplete loop)
    horizontal eight loop around the 2 vertical poles (P2 & P3) without overshooting beyond P1 & P4 35 points per loop
    (none for incomplete loop)
    b Fly-in through the entry gate (G1) and fly-out through the exit gate (G2) 25 points
    c Fly-in through the entry gate (G1) and fly-out above the exit gate (G2) 35 points
    d Fly-in through the Gate 3 (rectangular loop of 4m x 3m)
    and immediately return through Gate 4 (rectangular loop of 4m x 3m) (as indicated in arena diagram)     		50 points
    20 points for making it through only one rectangular loop.
    e - Safe landing before completion of 5 mins in the landing zone 35 points max
    ( lesser points depending on where it touches down)

    Teams will have to perform all the above maneuvers (excluding landing) at least once. The teams need not attempt the horizontal eight loop twice as mentioned in 'a' above. They may perform this maneuver only once and the points (25 or 35) are given in accordance with their performance. After they have completed the mandatory maneuvers, the teams can perform additional maneuvers in any extra time they have remaining before landing for extra points. A maximum time of 5 minutes will be given to take off, complete the maneuvers and land.
Judges decisions would be considered final in all cases.

Rules:

  1. Each team would be given 2 chances for both round 1 and round 2
  2. The best score is considered as per the scoring procedure mentioned above for each round
  3. The total of the two rounds would be used to declare the winner
  4. The timer will start from the moment the aircraft is in the air for both the rounds.

Revisions:

Any revisions to the Scope of the Competition would be intimated to all the participants via registered email and on the website.

General Information:

  1. The use of 2.4 GHz radio is required for all aircraft competing in the competition. If the participants want to use any other frequency, they will have to inform the organizers in advance.
  2. A limited number of 2.4 GHz radios will be available with the organizers for use by the teams. Teams who do not have access to radios can inform the organizers in advance to request use of these radios.
  3. Metal propellers are not allowed.
  4. The models can have powered take-off with a landing gear or can be launched manually by a person standing at ground level.
  5. Plane should be built from scratch and not purchased models.
  6. A team member can't be a part of more than one team at any one given competition.
  7. Bring your college/student I-Card at the time of competition.
  8. Both sides travelling allowance (max. 3rd AC train fare) for grand finale will be given to finalists.
  9. Accommodation will be provided by IIT Delhi
  10. Teams can reach the venue 1 day in advance for practicing
  11. All teams should be present in the campus by the evening of 11th April 2014
