Mission Statement

The mission of this student team is to develop a modular, scalable flight vehicle that can be operated autonomously. The vehicle should be able to control its own flight based on information gathered by sensors aboard the aircraft. The vehicle should also be able to carry interchangeable payloads to meet the needs of various potential customers. The team must provide complete documentation of the analysis, design, manufacturing, fabrication, test, and evaluation of this subsystem to a level of detail that a subsequent team can build upon their work with no more than one week of background research.

Continuation, Platform, or Building Block Project Information

The mission of the Aerospace Systems and Technology Track of projects is to develop the stands, platforms, propulsion systems, vehicles, and controls to be integrated as complete aeronautical and aerospace projects for use in a variety of education, research & development, and outreach applications within and beyond the RIT KGCOE. The collection of projects should use an engineering design process to develop modules and subsystems that can be integrated by subsequent senior design teams. This project, P07122, is the first senior design project to attempt an autonomous flying vehicle. The project will serve as a platform for future teams to build upon.

The mission of each student team contributing to this track is to develop or enhance either a subsystem for the METEOR family of projects or an Air Vehicle for the Micro Air Vehicle family of projects. Teams must also provide complete documentation of the analysis, design, manufacturing, fabrication, test, and evaluation of each subsystem and vehicle to a level of detail that a subsequent team can build upon their work with no more than one week of background research.

This roadmap will be initiated during the Fall Quarter, 2006-1, with nine related projects. Projects will have much stronger relationshps within the same family (P07100 or P07120). However, there is still expected to be significant overlap for all projects in the Aerospace Systems and Technology Track (P07100).

P07122 is a project within the Aerospace Systems and Technology Track, to develop a modular, scalable, autonomous flight vehicle. The focus of the students on this team is to design a mechanically innovative, autonomously controlled flight vehcile. The overall goal of this project is to be able to support multiple customers by designing for flexible and scalable payloads.

A number of other projects are intimately related to this project, as summarized in the list below.

Principle Sponsor or Sponsoring Organization

This project is supported by two different organizations. The RIT Honors Program has generously awarded an Interdisciplinary Research Grant to the honors students participating in this project. The intent of the RIT Honors Program is to enrich student's academic endeavors, further their personal growth through leadership, foster a sense of unity, promote service in the community, and develop skills lasting beyond their time at RIT. The RIT Electrical Engineering department will also be sponsoring this project with the aspiration of using the autonomous flight vechile for Ground Penetrating Radar (GPR) research.

Detailed Project Description

Customer Needs

First Sponsor Interview
Interviewer: Jason Enslin
Sponsor: Dr. Vincent J. Amuso
Date 15 September 2006, EE Conference Room

Dr. Vincent J. Amuso is a co-sponsor of senior design project P07122 as the electrical engineering department head. A one-hour interview was conducted with him on Friday, September 15 2006. Below is a transcript of the main aspects of the interview. Please note that Dr. Amuso is not a traditional customer in this case. He has agreed to sponsor a project that a senior design team presented to him. Consequently, the questions asked in this interview are adapted for his role in the project.

Interviewer: What does the electrical engineering department hope to gain from this project?

Dr. Amuso: I would like a piece of hardware that was designed and implemented by RIT students. I would like to be able to showcase the final product at RIT functions as well as take it with me to conferences, high school visits, etc. I would also like a detailed report of the design process to serve as a model for other students.

Interviewer: Is there a particular need that could be satisfied by the project or is there a certain function that you would like the final product to perform?

Dr. Amuso: The main thing is that I would like this project to serve as a platform for other students to build off of in the future. Also, if possible, it would be nice to have on board sensors aboard the aircraft to gather data. The project could possibly benefit my GPR work or maybe the METEOR project.

Interviewer: Are there any time constraints that you would like the team to meet?

Dr. Amuso: I would just like it completed by graduation 2007.

Interviewer: Are there certain checkpoints to be met during the course of the design?

Dr. Amuso: I would like bi-weekly status reports, including where you are in regards to your schedule and how much money has been spent relative to your budget.

Interviewer: Are there any particular components/systems that you would like to see us collaborate with or integrate with?

Dr. Amuso: Other senior design students have developed the PC104 microprocessor and I would like it if you could use it as the processor in your flight vehicle. This would be a great integration between two senior design projects.

Interviewer: Are there any intellectual property rights that the EE department will claim as a result of this project?

Dr. Amuso: No, this project will be open source. All information should be available to the public.

Interviewer: Are there any engineering specifications that the EE department would like met?

Dr. Amuso: The flight vehicle should have a half-mile radius range and fly at a minimum of 100 feet. There should be two-way communication between the ground and the aircraft. The aircraft should be autonomous with a pre-defined flight path that can be altered by real-time measurements gathered by the platform. There should also be a retrieval system on board the platform.

Customer Deliverables

Design and build a flight vehicle that can be controlled autonomously and carry a payload consisting of at least one picosatellite. This project should establish a platform that future students can build upon in subsequent quarters.

Customer and Sponsor Involvement

The team will be expected to carry out the vast majority of their interactions with the Team Guide (Dr. Amuso). Dr. Amuso will also be functioning as the sponsor and customer in this project as well, so he will be recieving scheduling and budget updates throughout Senior Design I and II as well. An undetermined faculty consultant specializing in aerodynamics or fluids from the mechanical engineering department will also be available for the team.
