Many of the accidents that occur in aircraft are caused by preventable errors. Many of these errors are listed below.
• Unbalanced or unbalanced mounting of the propeller
• Problems caused by the engine
• Body vibration
• Battery related problems
• Pilot error
Problem with the Dynamic Balance of Propeller
The propeller is one of the most important structures of the propulsion system that provides transport to the propulsion system. Although it is approached with micron precision during the construction of the propeller, the two blades can be of different weights. Considering that the propeller rotates at high speed, this will reduce the efficiency. In the pre-flight thrust tests, it may be noticed that the propeller is unbalanced and the propeller is not mounted correctly. In addition, before the thrust test is performed, it can be determined that the two blades are of the same weight with a propeller balancer. In this way, the aircraft is prevented from performing an accident-destruction or an inefficient flight.
Motor Failure
The motor is the most important structure of the propulsion system, which converts the electrical power from the battery into mechanical power. The motor is controlled by esc. Overloading causes the engine to overheat and reduce its efficiency. Overheating of the motor can also be caused by mounting instability and mechanical problems other than overloading.
Body vibrating
Material selection and assembly of parts with each other are very important in aircraft. Increasing vibration will make it difficult to control the aircraft and reduce the performance of the aircraft. The greater the amount of vibration, the more difficult it is to control and the greater the aircraft accident risk.
Battery Failure
The battery powers the propulsion system. Battery performance directly affects the flight time of the aircraft. For this reason, accident-breakdowns occur in aircraft due to sudden discharges in the battery or failure to determine the correct battery properties.
