The part was designed for a 3/8in diameter pipe. To maximize the circumferential strength, I used the 100% infill, and the number of perimeters required to eliminate the need for infill in the part that mates with the pipe itself.

@@TanmayChhatbar and which filament material? the levers looked quite flexible is it tpu? And layer height etc Other than that thanks a lot I will try to build something similar what you have :)

@@sarcasticfpv Everything was printed out of PETG. The levers clamp onto the pipe as a latch. With the current design, TPU wouldn't be able to clamp hard enough. Good luck printing it!

That's the idea! I've linked the repository for the code. Let me know if you have any suggestions

It was our own design. You might struggle to find a design online optimal for the competition, but try your luck.

@@TanmayChhatbar Thank you for your response. May I also know the process that you went through. As a rookie i dont have much information but i was thinking of Design-ansys tests- making-flight test and soo. And will balsa wood be good enough of a material and can we make some components like nose and other parts of material different from the rest of the aircrafts body?

​@@Kratos-hi1kx Start with aero, then structure, then electronics. Aero - Based on the competition's problem statement, estimate the lift you'll need. Your best friend in aero design is a software called XFLR5, which helps estimate flight performance characteristics. What matters here is maximizing CL/CD while maintaining stability. There are great tutorials on the software, but at a high level, you want to define a wing with the airfoil and its shape, at the very least. For stability analysis, you'll want to add a tail as well. The software is quite intuitive. airfoiltools is a good website to get data on airfoils. Structure - Choose foam for ease of design and manufacturing or balsa if you're confident that you won't have to fix it frequently (or any other common material) Start with hand-drawn sketches of aircraft that might suit the purpose. Design process - Print on a piece of paper the packaging/sizing constraints and draw around them. Then, you can move to more involved structural design. Electronics - Simplest to figure out. Just find a motor and prop combination that is most suitable for the problem (what matters here is both static and dynamic thrust). Then choose the rest of the electronics around this choice. Testing - Spend as much time as you can in testing! Testing is where you will want to figure out what the plane-pilot combination is comfortable doing. You don't want to guess how much weight your plane/pilot might be able to lift on the day of competition. Remember, testing involves breaking things. If you're not breaking things, you're not pushing the capability of the plane. So, keep spares, for as much as the plane itself. Based on the competition's problem statement, estimate the lift you'll need.

@@TanmayChhatbar Thanks on this valuable info dump! My team if pretty much done with the design right now, for us the problem statement is to make a commercial aircraft that can carry the golf balls inside the craft, loading and unloading should be mechanical and not touching with hands. So we were thinking of opening the nose of the plane like C5 galaxy with two servos along with hinges. The aircraft is not to exceed 1kg and T/W <= one they say. Our aircraft would weigh around 800-1000g the wing chord is around 24cm(rectangular) aircraft length is 80cm . We are now supposed to submit abstract of 15 pages . Any tips on that? I have hand sketches of 6 sheets i think shouldn’t i include that along with the abstract. Dont know what I should write tho. Yeah and we are going with foam board and balsa for longerons and ribs and some pla for reinforcements maybe even some aluminum rods will have to test all those out after making the plane.

​@@Kratos-hi1kx For the abstract, you can add the following in my opinion: - final drawings - photos of the build - detailed design of components for satisfaction of requirements - detail on comparison of solutions and justification of why you made the decisions you made (tradespace exploration), eg. material, wing geometry, packaging, loading. I'll suggest you use PETG or ASA (or ABS) for 3D printed parts instead of PLA. PLA tends to warp in the sun, and warps with stress over a long time anyway and is not really a good material for anything structural. Consider CF rods instead of aluminum rods. They'll save you some weight. Also, consider adding winglets. They help improve wing efficiency especially for rectangular and large aspect ratio wings significantly.

You can fly RC airplanes with permission at Mahalaxmi race course if I remember correctly.

Coroplast is stiff, but buckles easily, but you can make your plane using this. Just remember the disadvantages. The organisers might provide pilots to fly your plane on your behalf, I'm not sure. I know Mumbai offered it when I went, but it's better to confirm with the organisers. I assume by elevation, you mean dihedral. It improves aircraft stability, at the cost of L/D efficiency. For this compentition, I'd say it is pilot's choice. I would go for 5-7deg dihedral if you want stability, no dihedral if you're experienced.

@@TanmayChhatbar thanks bro

It's best you research high lift, low Reynolds airfoils to find your answer.

@@TanmayChhatbar thankyou for your answer,and can u tell which motor did u use for your aircraft

Balsa wood for the wings. Foam for the fuselage

@@TanmayChhatbar What was the Wing Capacity Load (WCL) and weight of the plane and the wing dimensions as well?

@@zabirakhterhussain2991 Plane weighed round 760g. Wing was as wide as regulation allowed.

@@TanmayChhatbar How much KV motor was used?

1.2m

@@TanmayChhatbar are you taking part this year?

@@piyushaneejwal6876 Nope. If you are, good luck!

It was 0.75 for our year.

@@TanmayChhatbar and what about the payload how much those 28 golf balls weights?

@@prathameshkalaskar9250 1 golf ball is 46gm. 46*28=1288gm

If I remember correctly, it was a 2207 2300kV T-Motor with a 7x6 propeller, 40A ESC, 3S battery.

Golden commentary as well!

Criterion was how many hit the target circle. It didn't matter if they bounced away after. These golf balls tend to roll and bounce pretty well, so it'd be naive to judge based on the number of balls that remain in the circle.

@@TanmayChhatbar ok bhaiya
