Project LeadAY: 2008-2 – 2008-3

Airframe A

Matt Greco

P09231

The Airframe A project will build 6 of the Aero Design Team instructional planes. This design is smaller than the proposed vehicle platform of the family and cannot carry a large payload. However, they can be used by the

other groups to test lightweight, initial concepts of their projects. This design should be modified as needed, and used to characterize flight dynamics to assist in future design work. The high level goal of this project is to develop a robust aero platform with a high success rate and extreme ease of interchangeability of costly

components. A large portion of work will be in optimization and redesign.

Airframe B

Josh Wagner

P09232

The Airframe B project plane will be modeled after the Aero Design Team's Split Decision aircraft. The payload specifications of the aircraft will be selected as the standard for this and future designs. The goals of this project are to complete and optimize the design, make it more rugged, and ensure that it provides a suitable platform

for our project.

Measurements

Michael Skube

P09233

The Measurements group will purchase and test a variety of pressure, temperature, and acceleration sensors. Focus will be not only on calibration and implementation of the sensors with a data acquisition system but also decide, with input from the Airframe and Controls groups, the locations for the sensors so they can provide the

necessary information to control the airframe. Additional monitoring and measurements will be done on additional onboard airframe properties.

Payload

Steve Sweet

P09235

The Payload group will interact closely with the Airframe B and the Aerial Imaging teams to finalize payload specifications that are suitable for both projects. This team will also design concepts for bomb-bay doors. The doors will remain closed to reduce drag and protect the imaging equipment when not in use, and will open to expose the payload when it is needed. These designs will be incorporated into the "A" trainer planes to test

their viability. The best solution will be scaled up and incorporated into the larger "B" plane. The system should be rugged, lightweight, and simple.

Controls

Jim Hunt

P09234

The controls project will consist of taking a Model R/C Plane Dynamics by use of a wind tunnel. The wind tunnel will be used for finding the aerodynamic coefficients, which can then be applied to the plant model of the

control system for the UAV that will be under development. The other focus will be on implementation of the plant model and wind tunnel testing to actual controllers.
