Development of light weight propeller bracket

Development of light weight propeller bracket / Mohamad Rukaini Mazlan
Tujuan tesis ini adalah untuk merekabentuk, menganalisis dan membuat pendakap kipas ringan yang menyumbang kepada kestabilan pesawat ringan Merlin kerana reka bentuk yang sedia ada adalah lebih berat. Masalah ini menyebabkan pesawat tidak stabil semasa penerbangan. Penyelidikan ini memberi tumpuan kepada jisim CAM100 yang berlebihan berat badan akibat reka bentuk pendakap kipas. Reka bentuk baru dibuat dengan menggunakan pengoptimuman topologi dari perisian ANSYS. Struktur yang dioptimumkan kemudiannya diubah menjadi unsur kekuda. Struktur dan kerangka ruang utama telah menjadi penyelesaian yang lebih disukai untuk masalah memaksimumkan kecekapan struktur kerana ia membolehkan peningkatan yang sangat besar dalam lenturan ketegaran dan kapasiti beban beban ditambah nisbah kekuatan kepada berat. Kaedah reka bentuk baru seperti kaedah elemen kekuda dan struktur komposit digunakan sebagai reka bentuk baru untuk struktur yang mempunyai pengurangan berat. Struktur kemudiannya menganalisis dengan menggunakan kaedah elemen Finite dan dibandingkan dengan kaedah analisis. Reka bentuk terbaik kemudian dibuat untuk kekuda struktur unsur dan struktur bahan komposit. Pengurangan berat badan terakhir dibawa ke campare yang mempunyai pengurangan berat badan yang lebih tinggi Hasilnya menunjukkan bahawa reka bentuk baru mempunyai pengurangan berat badan yang memberikan kestabilan pesawat lebih. _______________________________________________________________________________________________________ The purpose of this thesis is to design, analyze and fabricate the light weight propeller bracket which is contributing to the stability of the Merlin light aircraft because the existing design are overweight. This problem cause the aircraft not stable during flight. This research is focus on the mass of CAM100 that are overweight due to the design of propeller bracket. The new design is made by using topology optimization from ANSYS software. The optimized structure is then converted into the truss element. Truss structures and space frame have been preferred solution to the problem of maximizing structural efficiency as they allow for very large increase in the flexural rigidity and load carrying capacity plus it has strength to weight ratio. The new design method such as truss element method and composite structure are used as new design for the structure which have weight reduction. The structure then is analyzed by using Finite element method and it is compared with analytical method to ensure there is no failure during engine operation. The best design then fabricated for truss element structure and composite material structure. The final weight reduction is taken to compare which has higher weight reduction The result show that new design has weight reduction which give aircraft more stability.
