Abstract

The challenging and encouraging nature of a research environment can contribute to the successful application and retention of knowledge for a college student. It is important for engineering students to realize the benefits of participating in a research laboratory during their undergraduate career. This paper presents the design, construction, and testing of a thrust stand to demonstrate the core principles taught in advanced engineering courses. The thrust stand was designed to facilitate the testing and evaluation of different types of motors, both gasoline and electric, commonly used in small Unmanned Aerial Vehicles (UAVs). As UAVs evolve from being simple remote-controlled toys to serious testbeds for data collection and research platforms (flight control, surveying, etc.), so do the requirements on characterizing their performance. This exercise allowed the student to put into practice the knowledge gained in various courses during their current undergraduate career, such as statics, dynamics, computer science, electrical engineering, computer aided design, and general machine shop practices. This experience took place in a research lab and introduced the student to the iterative engineering design process. The experience taught the student how to proceed from a set of broadly defined requirements, iteratively design a fully functional system, and work with a team to reach a common goal. This project was conducted by a student in their junior year, majoring in aerospace engineering at University. For this educational research project, the student designed, built, and tested a thrust stand which was used to measure the thrust produced by UAV motors. To calibrate the device, the three structures were be mounted together on the same table. To test the motor, the calibration structure was be removed, and the motor was be mounted. This modular design allows the student to run tests inside and outside the laboratory. The testing showed that there was approximately an error when loading and an error when unloading the device. Relative uncertainty (bias and random uncertainty) was less than 3% for the thrust test. Preliminary calculations predicted the motor would produce between 14 and 16 kg or 137.34 and 156.96 N, respectively. The experimental results validate the expected thrust output from the motor.
