Introduction The MAE2 Klein Flugtag consists of two competitions. The first competition requires design and construction of an aerial vehicle that is intended to maximize vertical flight distance (altitude). The second competition requires an aerial vehicle to maximize horizontal flight distance (range). Vehicles in both competitions are propelled by compressed air that is stored in a portable tank. Pressure in the air tank is kept at approximately sixty pounds per square inch, but this pressure may vary as each competition progresses. Vertical Flight Vehicle The Spacely Sprocket Vertical Flight (SSVF) vehicle is shown in Figure 1. The vehicle resembles a full-scale rocket, with main components including the fuselage body and tail fin assembly. The fuselage body is constructed from material cut from a Tyvek shipping envelope. Tyvek was chosen for the fuselage because it is stronger and lighter than regular copier paper. The SSVF fuselage has a 2.1 cm diameter. It fits tightly over the one-half inch diameter Polyvinyl Chloride (PVC) pipe that is used as the vehicle launch tube. No attempt was made to optimize the gap between the fuselage and the launch tube. Fuselage length was chosen as 21.6 cm. This length results in a fuselage body fineness ratio of about ten. With this fineness ratio, the profile drag coeficient (based upon fuselage cross 2

sectional area) is about 0.08. Lower drag coefficient values could be obtained with a shorter fuselage length, but a shorter fuselage length would also reduce boost velocity. A shaped styrofoam nosecone is mounted on the top of the fuselage. The joint between fuselage and nosecone has been sealed with epoxy adhesive. A strong epoxy adhesive was used for this joint because it must withstand the direct force of the compressed air launch. The SSVF is equipped with four tail fins that are aligned at ninety degree intervals. The four tail fins are included in the design to insure static longitudinal and directional stability. Each tail fin has a surface area of approximately 7.5 cm
