The mission of this year's team is to complete the surveillance portion of the 2007 International Micro Air Vehicle Competition by improving, but not redesigning, last year's MAV. To accomplish this, the customer set the two following objectives: (1) rebuild and flight test last year's MAV, and (2) introduce new concepts to improve last year's MAV. The team must provide complete documentation of the analysis, design, manufacturing, fabrication, test, and evaluation of the new MAV to a level of detail that a subsequent team can build upon their work with no more than one week of background research.

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, P07121, is the fourth in a series of senior design projects that will likely continue in the future.
The mission of the student team contributing to this track is to develop and enhance an Air Vehicle for the Micro Air Vehicle family of projects. The team 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.
P07121 is a project within the Aerospace Systems and Technology Track, to develop a Micro Air Vechicle to successfully complete this year's Micro Air Vehicle Competition. The focus of this year's MAV will be to incorporate the research and major redesigns from last year's MAV with further improvements to the propulsion system and flight dynamics. Flight testing will be a major source for improvements. The goal of this year's team is not to win the competition but to meet all key customer needs and to continue the trend of improving MAV's at RIT.

The mission of this project to develop a Micro Air Vechicle to successfully complete this year's Micro Air Vehicle Competition. The competition will require the MAV to fly 600 meters, photograph a 1.5-meter sized symbol on the ground, fly another 300 meters, capture a second 1.5-meter sized symbol, and return to the launch site.

Customer and Sponsor Involvement
The team will be expected to carry out the vast majority of their interactions with the Team Guide (Dr. Kozak). In the case that an EE faculty member joins the team, MEs will conduct most of their work with Dr. Kozak and EEs will conduct most of their work with the EE faculty member. Since Dr. Kozak is the customer, all questions regarding scope or objective should be directed to Dr. Kozak, and it is anticipated that Dr. Kozak will be accessible for the duration of senior design.
Regulatory RequirementsThe MAV should comply with all rules of the International MAV Competition.
Project Budget and Special Procurement ProcessesThe Boeing Company has allocated $2,000 to the MAV Senior Design Team for AY06-07. The team is expected to stay within its budget, and it is expected that expenditures be in-line to satisfy customer requirements and project objectives.
The team will be required to keep track of all expenses incurred with the project.
Purchases for this track will be run through the mechanical engineering procurement system. Dave Hathaway (Operations Manager) for the ME department will be point of contact for most purchases associate with this project and this track. It is recommended that each team appoint one person to act as the purchasing agent for the team, and that all interactions between the team and Dave go through the single purchasing agent. The team is responsible for providing all receipts, copies of invoices, shipping documents, and proper use of tax exempt forms, etc.
- The total development budget for the Micro Air Vehicle Project is not anticipated to exceed $2,000 during AY06-07.
Intellectual Property Considerations
All work to be completed by students in this track is expected to be released to the public domain. Students, Faculty, Staff, and other participants in the project will be expected to release rights to their designs, documents, drawings, etc., to the public domain, so that others may freely build upon the results and findings without constraint.
Students, Faculty, and Staff associated with the project are encouraged to publish findings, data, and results openly.
|1||Lift Coefficient||> 0.49|
|2||Drag (N)||< 0.076|
|3||Roll Moment Coefficient||TBD*|
|4||Thrust to Weight||> 1:1|
|5||System Power (W)||> 16.65|
|6||Length (cm)||< 25.4|
|7||Weight (g)||< 96|
|8||Resolution (lines)||> 300|
|9||RF Power (mW)||> 80|
- Since last year's team did not record a value for roll moment coefficient, and target will need to be established from early flight tests.
- The following are guidelines established by previous senior design teams and should be considered during design and manufacturing phases of this year's project.
- Vertical tail design is key component to yaw stability.
- Control surfaces should be added for pitch and roll control and to minimize drag effects.
- MAV must be stable in pitch, roll, and yaw.
- Design in side-thrust to control yaw.
- Aircraft planform should minimize tip vortices.
- Aircraft should maintain stability/lift/drag for the duration of the flight.
- Wing skin/control surfaces should integrate fully with wing skeleton, be effective in dynamic loading, and meet flexibility/rigidity needs.
- Component housing must protect expensive components, have static center of gravity, and integrate completely with wing skeleton and components.
- Flying of the MAV should not be conducted in crowded areas or by inexperienced users.
