Расчет на прочность модели «c» беспилотного летательного аппарата при различных условиях эксплуатации

Abstract

The article describes the methodology analytically determining the stress state of airframe components of air drone. Additional element of rigidity of the wing is calculated. Physical and Mathematical simulation of the stress state of the wing which is strengthened tubular longeron of the airframe of air drone is performed using ANSYS software. As a result of theoretical calculations and simulation in ANSYS software, extreme angle of attack (18°) which had been found experimen- tally is confirmed. Extreme angle of attack is proposed to software developers of the autopilot mechanism to prevent emer- gency situations. The calculations on the strength allow ensuring reliable operation of air drones for the given conditions.
