First Principle Approach to Modeling of Primitive Quad Rotor
Sudiyanto, Tata,Muljowidodo, Muljowidodo,Budiyono, Agus The Korean Society for Aeronautical and Space Scie 2009 International Journal of Aeronautical and Space Sc Vol.10 No.2
By the development of recent technology, a new variant of rotorcrafts having four rotors start drawing attention from aerial-robotics engineers more than before. Its potential spans from just being control device test bed to performing difficult task such as carrying surveillance device to unreachable places. In this regards, modeling a quad-rotor is significant in analyzing its dynamic behavior and in synthesizing control system for such a vehicle. This paper summarizes the modeling of a mini quad-rotor aerial vehicle. A first principle approach is considered for deriving the model based on Euler-Newton equations of motion. The result of the modeling is a simulation platform that is expected to acceptably predict the dynamic behavior of the quad-rotor in various flight conditions. Linear models associated with different flight condition can be extracted for the purpose of control synthesis.

The modern electrical industry in Indonesia faces escalating energy demands, projected to reach 1,413 Terawatt Hours by2060. Meeting these demands necessitates enhancing the quality of electrical transmission systems, particularly insulators, witha focus on local materials to reduce dependency on imports. Porcelain Alumina Ceramic Insulators (PACI) offer promisingalternatives due to their high resistivity and mechanical strength. This study investigates PACI synthesis using locally sourcedmaterials: kaolin, ball clay, alumina, and feldspar. Chemical analysis confirms alumina as the primary component (99.7%Al2O3), while other materials contribute to silica content. Fabrication involves crushing, drying, grinding, sieving, and sinteringat 1280 °C, yielding specimens (K1S, K2S, K3S). Material characterization employs XRD, XRF, SEM and electrical testsreveals phase compositions, morphological changes, and electrical properties. K3S, rich in feldspar, exhibits superior materialstrength (74.62 N/mm²) and hardness (190 N/mm²) with limited conductivity. Utilizing local resources for PACI productionpromises economic benefits and reduces import dependence. This study illuminates the interplay between material compositionand resulting properties, offering insights into ceramic synthesis for improved electrical infrastructure.
