Design and manufacturing of an UAV G1

Objectives of the project:

1. Design of an Unmanned Aerial Vehicle, by means of theoretical analysis and applied software analysis of the subsystems of:

  • aerodynamics,
  • structure,
  • flight mechanics,
  • mechanic and graphic design.

2. Manufacturing of the UAV model to be tested in UEM wind tunnel and to be flown outdoors. The aims of the payload are mapping the ground elevation and measuring the flight altitude.

Going back in time and taking a design and structure from the 1940s to create an innovative and powerful UAV that simplifies the process of measuring the altitude and ground elevation. The UAV is designed uniquely to fulfil the requirements and regulations given while being limited to a budget of three hundred and fifty Euros. Apart from not exceeding the budget, the UAV is required to have a maximum wingspan of 1.5m, have a low cruise speed, and be as light as possible.

The project began by brainstorming ideas and coming up with a conceptual design that fits our budget and requirements. The measurement of the ground elevation from an aircraft is achieved by including a sonar device and a barometer. The position of the UAV is determined by a GPS device.
The design and structure was one of the most complicated parts of this project. It required a substantial amount of CATIA knowledge and ability to work in teams. The five main design requirements, which guided our development process, were supplied to us by the professors. The design of the product was divided into the wing, fuselage, tail, landing gear, power plant, electronics and controls. Every single one of these parts was further divided into subparts.

At the end, an evaluation was performed in order to measure the efficiency and reliability of the design. Further, a preliminary structural analysis was done. This evaluation was governed by testing the obtained results (from research and professors) and trying to make assessments based on the acquired knowledge. Finally, future steps of what should be done and how the project will be moving forward were discussed in detail. One of the most important discussion topics was the facility of manufacturing and the final decision of what manufacturing processes to choose. 3D printing is still a the main option for some components but has a very high price compared to the traditional ways of manufacturing. The next step will be to plan how to market and sell the UAV to make it standout in the market of UAVs and aerospace products. Competition is high, for this reason a low budget will allow for a low selling price which will give our UAV a competitive advantage.
