Stress and strength analysis of a control flap structure for ultra-light helicopter

Stress and strength analysis of a control flap structure for ultra-light helicopter / Athifah Fakhirah Muhammad
Tujuan tesis ini adalah untuk menganalisis tekanan dan kekuatan, merekabentuk, dan membuat struktur sirip kawalan untuk sebuah helikopter ultra ringan (ULH). Tesis ini menyediakan kaedah terperinci dalam menganalisis tekanan dan kekuatan sirip kawalan bagi helikopter ultra ringa dan juga reka bentuk terperinci sirip kawalan. Sirip kawalan ini direka supaya mampu bergerak ke kanan dan ke kiri dengan bantuan pedal kawalan. Sirip mestilah dapat menyokong beban daya tujahan ke bawah yang dihasilkan oleh bilah pemutar helikopter ultra ringan ini dengan jumlah yang dianggarkan sekitar 10 N. Projek ini menggunakan bahan komposit iaitu kaca gentian. Bahan yang dipilih mestilah dapat menyokong beban yang dikenankan keatas sirip kawalan struktur ekor. Analisis simulasi dilakukan dengan menggunakan salah satu reka bentuk dibantu computer (CAD) iaitu perisian SOLIDWORKS 2018 x64 Edition. Penyiasatan dilakukan untuk memerhati sama ada struktur sirip kawalan dapat menyokong beban yang diletakkan atau gagal untuk melaksanakan sebagaimana perlu berdasarkan beberapa jenis ujian simulasi. Selain daripada analisis simulasi, pendekatan analisis pengiraan juga dikira untuk membandingkan dan mengesahkan struktur sirip kawalan. Perbezaan peratusan diantara simulasi dan pengiraan juga diambil kira. Perbezaan peratusan antara simulasi dan pengiraan adalah 25 %. Untuk menyiapkan projek ini, bahan and peralatan yang digunakan dalam pembuatan sirip kawalan boleh didapati di bengkel dan makmal Aeroangkasa. _______________________________________________________________________________________________________ The purpose of this thesis is to analyse the stress and strength, design, and fabricate the control flap for the tail structure of an ultra-light helicopter (ULH). This thesis provided a detailed method in analysing the stress and strength of the control flap of an ultra-light helicopter and the detailed design of the control flap. The control flap is designed so that it is capable to move to the left and the right assisted by the control pedal. The flap must be able to support downwash forces produced by the rotors blade of the ultra-light helicopter where the total estimated load is about 10 N. This project uses the composite material which is fiberglass. The selection of material able to withstand the load applied on this control flap of the tail structure. The simulation analysis is done by using one of the Computer-aided Design (CAD) which is SOLIDWORKS 2018 X64 Edition software. The investigation is performed to observe whether the structure of the control flap can support the applied load or fail to deliver as required base on the several types of simulation testing. Besides the simulation analysis, the analytical approach is also calculated to compare and verify the structure of the control flap. The percentage difference between simulation and analytical also calculated. By comparing both of these simulation and analytical approaches, the percentage difference is 25 %. In completing this project, the material and equipment used in fabricating this control flap are available in the Aerospace workshop and laboratory.
