Boeing - IIT National Aeromodelling Competition

Dates: Will be announced shortly
Venue: Open ground at IIT Delhi

Problem Statement

The final round at IIT Delhi is for the winning teams in the 4 zonals conducted at IIT Bombay, IIT Kanpur, IIT Kharagpur and IIT Madras. The teams must design, fabricate and demonstrate a fixed wing aircraft system that can perform tasks mentioned in the problem statement with given constraints.

Design Constraints:

1. The competition requires participants to design and fabricate an RC aircraft. Readymade models, like RTF, ARF, BNF etc., are not allowed.
2. T/W <=0.75 without payload (If excess thrust is measured, it will be neutralized by adding weight below the aircraft at center of gravity)
3. Propeller diameter should not be greater than 13 inches
4. Total wingspan should be a maximum of 1.2 m
5. Only electrical motors are allowed. The use of IC engines or any other means of providing thrust is prohibited.
6. Use of gyroscopes (gyros) and programming assistance is prohibited.

Abstract Submission

1. All participants need to submit an abstract on their aircraft, which should be no longer than 15 pages (A4 size 1.5 line spacing) with standard formatting. The Abstract must document the basic design of the aircraft (dimensions, wing areas, velocity, etc.) and should also explain how their design is suitable for the given problem.
2. Along with the abstract, participants also have to send a zip file containing at-least 5 and no more than 10 photographs of the aircraft while it is being built
3. The Abstract has to be submitted as per the format mentioned. Click here for abstract format
4. The Abstract has to be submitted 20 days in advance of the competition date
5. The abstract must be submitted as per the format mentioned by sending an email to boeingcompetition2020@skyfilabs.com

Theme

The theme for the final round is Multi-Payload Carrying & Dropping Capability.

Problem Statement

The aircraft should carry two or more payloads (golf balls of weight - 45g, diameter - 43mm will be supplied by the organizers during the competition) and drop them in 2 separate instances in a circular drop zone of 30m diameter.

• The first drop should be performed after a minimum flight time of 45 seconds from take-off
• After the first drop, the aircraft should continue to fly and drop the remaining payloads after flying for a minimum of another 45 seconds.
• Teams that drop equal number of payloads in both the attempts will get higher points (see formula below). Example: If the aircraft is carrying 20 balls, dropping 10 in each attempt will give more points instead of dropping 1 and 19 balls in the 2 attempts.

Score

WF1 = Weight of payload that falls in the drop zone in attempt 1
WF2 = Weight of payload that falls in the drop zone in attempt 2
WR1 = Weight of payload that is released in attempt 1
WR2 = Weight of payload that is released in attempt 2
WA = Weight of aircraft without payload
min(a,b) = Smaller of the two values a and b

• Payload Mounting - All the payloads in the aircraft should be loaded as independent objects. They should not be packed or joined as one bigger payload (e.g. sticking them together or dropping a box with multiple payloads in it are not allowed).
• The drop zone is at 40m from the take-off and landing zone. (For better understanding of the arena, refer to the illustration given below).
• A maximum time of 5 minutes will be given between the take off and the landing and the aircraft should complete the drop and land within the time limit.

Rules for final round

1. Each team would be given two attempts. Best score from both attempts will be considered as score for each round. If there is a tie, winner will be decided by a separate round framed by the Judges on the spot.
2. Same aircraft should be used in both the attempts and it should be the same one in the abstract. In case of damages during the competition, teams can repair the same aircraft but are not allowed to use a replacement. The repaired aircraft should be ready in time for the next attempt.
3. The arena will be in an open ground at IIT Delhi
4. Travelling allowance (max. 3-tier AC railway fare) will be provided to all members of the teams participating in the final round. The participants must submit printed copies of their tickets with the fare to avail the same.
5. Accommodation would be provided at IIT Delhi for the participants
6. Teams can reach one day in advance to IIT Delhi for practicing
7. All teams must report at IIT Delhi campus by 4 PM on the day before the final round and must be present for the briefing at the venue at 5 PM on the day before the final

General Guidelines

1. The use of 2.4 GHz radio is required for all aircraft competing in the competition.
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. Receivers installed in the aircraft must be in 'receiver mode only'.
4. All the systems (Servos, motor, etc.) will be checked by organizers for functionality before the competition. If found not working, teams will be dismissed from the competition.
5. Pilot can position himself at any point in the arena to fly the aircraft during the rounds
6. In view of safety requirements, if a pilot flies out of the designated flying zone which includes overhead of the event organizing and control section, as mentioned at the venue, the team will be disqualified and must immediately turn back and land safely.
7. Teams are suggested to carry additional components (motors, batteries, propellers etc.) as needed to avoid last minute surprises at the venue. You will lose time/ attempt if you are not ready at the time of your turn.
8. Teams are suggested to not share/ borrow any part of your aircraft (motors, ESC, Battery etc.) with/ from other teams. Each team is expected to carry all the equipment needed to participate in the competition.
9. Metal propellers are not allowed
10. The models can have powered take-off with a landing gear or can be hand-launched
11. A participant cannot be a part of more than one team
12. The team members should be the same as in the zonal rounds. No changes will be allowed
13. Participants must bring their college/student Identity Card, in addition to a bona-fide certificate from the college/institution

Revisions:

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