  3. MINIATURE UNMANNED AERIAL VEHICLE The Project • Goals: To design and manufacture a relatively cheap, feasible and revolutionary aircraft with versatile control capabilities. • Flight • Lift off & Landing • Propulsion for added flight time • Stability & Control • Powerful Maneuverability • Air Flow through counter-rotating ducted fans • Gear & Cam System • Wireless/Remote Control System • User Friendly GUI • - Integration of Electronic Devices http://www.fit.edu/projects/muav2

  4. MINIATURE UNMANNED AERIAL VEHICLE Limitations • Monetary • - Knowledge & Experience • - Facilities (construction & testing) • - TIME http://www.fit.edu/projects/muav2

  5. Brainstorming Sessions Aerospace constraints due to ECE designs General aerodynamics and flight mechanics centered around helicopter and ducted fan design theory Brian Wright MUAV I information (design flaws, engineering management) Online Information www.uavforum.com Online Hobby Stores (parts details) Various sites with published information on UAVs Library Materials Aerodynamics of V/STOL flight. McCormick, Barnes W. Rotary Wing Aerodynamics. Stepniewski, W. Z. Helicopter Engineering. Young, Raymond A. Helicopter design and data book. Dzik, Stanley J. MINIATURE UNMANNED AERIAL VEHICLE Research Areas and Assists http://www.fit.edu/projects/muav2

  6. MINIATURE UNMANNED AERIAL VEHICLE Research Areas and Assists • Library Materials • Testing and Experimentation • Aerodynamic forces and moments of body and ducts • Vibrations and heat transfer from engine • Thrust achieved on ground and in flight • Trial and Error • Change design aspects as project moves along (i.e. center of mass, power output, flight control input/output, body shape) • Coursework Theory • Aerodynamics and Flight Mechanics, Aerospace Structures, Air-breathing Engines, Engineering Mechanics, Thermodynamics Fluids 1, Mechanical Vibrations • Professors • MAE Department Faculty http://www.fit.edu/projects/muav2

  7. MINIATUREUNMANNEDAERIALVEHICLE Concept Tradeoffs Viable Options from brainstorming sessions • Use 2 counter-rotating coaxial fans (Most Feasible) • Use 2 fans side-by-side for lift • Use alcohol engine (Most Feasible) • Use of electric engine instead of the alcohol engine • Tethered flight using power cord from a.c. main to power • Use of pendulum type device to stabilize craft • Use of 2 step gyros to stabilize flight http://www.fit.edu/projects/muav2

  8. MINIATUREUNMANNEDAERIALVEHICLE Concept Tradeoffs • Thrust of each engine can’t be varied. Therefore, yaw stability by varying thrust won’t be possible. • Power losses in gears reduce thrust • Aerodynamic Interference of Fans • Roll stability by varying thrust won’t be possible since fans are coaxial. http://www.fit.edu/projects/muav2

  9. MINIATUREUNMANNEDAERIALVEHICLE Materials • Carbon-Fiber composite for outer body • will withstand tensile and bending loads • provide an outer aerodynamic surface • Foam for inner body • will withstand shear forces • will also hold the internal components in place http://www.fit.edu/projects/muav2

  10. MINIATUREUNMANNEDAERIALVEHICLE Modeling and Simulation Use of canned CAD software • Solidworks, ProE, and ProM • for modeling and development of Mathematical model of the craft • Stress/strain analysis • In normal straight flight mode • During flight that is unleveled and with sharp turns • Determining C.G. of craft • How to balance the craft so center of lift and C.G coincide • Craft strength • Impact resistance http://www.fit.edu/projects/muav2

  11. MINIATUREUNMANNEDAERIALVEHICLE Modeling and Simulation • Hand calculations will be drawn up as well: • initially using Newtonian analysis • For thrust vectoring • Pendulum type motion recreation and observation • then focusing on vibrational and structural analysis • based on thrust and induced torques within craft http://www.fit.edu/projects/muav2

  12. MINIATUREUNMANNEDAERIALVEHICLE Modeling and Simulation • Construction of Craft • initial construction of mold using foam • Internal structure however will be made of foam • Easier to fix internal components • Lightweight, strong, and compact • Most important – Cheap • Outer shell of fuselage made from Carbon fiber • Strong and very lightweight • Resistant to most types of physical damage http://www.fit.edu/projects/muav2
