Generativno oblikovanje in izdelava adapterja za krilo letala na daljinsko vodenje s procesom selektivnega laserskega taljenja

Jerman, Tit (author), Govekar, Edvard (mentor)

V zaključni nalogi smo z metodo generativnega oblikovanja izboljšali obstoječ adapter na krilu letala na daljinsko vodenje. Pri tem smo se osredotočili na zmanjšanje mase adapterja pri enakih obremenitvah. V delu najprej predstavimo teoretično ozadje dodajalnih tehnologij ter opišemo tehnologijo selektivnega laserskega taljenja ter metodo generativnega oblikovanja. Nato predstavimo adapter za krilo letala in njegovo oblikovanje s ciljem zmanjšanja mase. Oblikovani adapter smo pripravili za 3D tisk ter ga izdelali s procesom selektivnega laserskega taljenja. Izdelani adapter ima 4x manjšo maso, prenese pa enake obremenitve kot obstoječi. Ugotovili smo tudi, da je izdelava oblikovanega adapterja s procesom selektivnega laserskega taljenja cenovno primerljiva z izdelavo s 5-osnim CNC rezkarjem.

• Title: Generative design and fabrication of a remote-controlled aircraft wing adapter using a selective laser melting process

Abstract

In the final thesis, we improved the existing remote control aircraft wing adapter using the method of generative design. Our focus was on reducing the weight while maintaining the same load-bearing capacity. In the thesis, we presented the theoretical background of additive manufacturing and described the process of selective laser melting as well as generative design. Next, we presented the aircraft wing adapter and its design objective of mass reduction. We prepared the adapter for 3D printing and printed it using selective laser melting technology. The improved adapter has 4 times less mass while being able to withstand the same loads as the original one. Additionally, we found that manufacturing with selective laser melting process is cost comparable to 5-axis CNC milling.
