Redesign the engine frame of Midour III aircraft

Abstract

Midour III is a full size wooden amateur-build aircraft which is currently being built at the airfield of Tarbes by Vélivole Association. Unfortunately, the airfield is placed in a very sensitive surrounding which is the center of the city of Tarbes, hospital, highway and a golf field. This fact leads to the problem which is an extensive noise of the Midour III aircraft. The solution proposed is to use a different muffler (sound attenuator) to the engine exhaust system. Unfortunately, the new muffler will interfere with the original frame for the engine. The solution of this problem is to scan the engine with the new exhaust system and assemble it with the existing engine frame design. The next step is to find the interference and solve it by redesigning the frame. Therefore, the main objective of the project is to redesign the frame of the engine in order to fit in a new muffler before 29th of June 2017. The project team, called Midour III Gliders, consisting of multinational members, is working as a part of the European Project Semester for the Ecole Nationale d’Ingénieurs de Tarbes to solve this problem. The research and the planning process have been presented in the Intermediate Report and the monitoring part of the project management and solutions of the problem will be proposed and explained in this final report. The core work of the project have been going since the Intermediate Report (11.05.2017) until the 29th June 2017.
