RC Model Performance Analysis for Airworthiness Certification

Abstract

Military UAV design and production must follow STANAG 4703 which is the Airworthiness for small UAV its weight less than 150 kilogram. This regulation is well-known and being used in various industry. In general takeoff distance is a critical phase of any aircraft because speed of the aircraft is near stall speed. Thus, to get the airworthiness of the aircraft, developer needs to make sure that their design can meet the requirements. The pre-calculation of this data is crucial to avoid unnecessary damage and STANAG allow to get this data from trustable program. Therefore, this research develops a MATLAB calculation using muti-step numerical analysis to calculate takeoff performance of the aircraft. This program has been tested to 4 aircraft compose of 2 general aircraft and 2 mini-UAV. The error of the result is less than 10%. Hence, we can use this program to calculate any other aircraft to get takeoff performance for airworthiness.
