ES 100 Micro Aerial Vehicle Group 1 Michelle Helsel, Austin Dickey, Alsia Plybeah, Dylan Carlson, Peter, Lucilla Calderon Slide 2 Introduction The Micro Aerial Vehicle (MAV) is a model Unmanned Aerial Vehicle (UAV) using microelectronics UAV control commands originate from remote locations, such as a computer system, a pilot in another vehicle, or a technology team miles away We decided to build our MAV from scratch using our background knowledge Slide 3 Objectives We are tasked with designing and testing a micro aerial vehicle that will: Cost less than $250 Fly 5+ minutes without recharging its energy source Take off from and land on the ground Can be controlled remotely by a 2.4G Hz radio transmitter in a 100x50x30 space And weigh less than 450 grams The Mission: Endurance - fly as many figure 8 paths around two pylons separated by 50 in five minutes. Slide 4 Gantt Chart through today Slide 5 Gantt Chart for upcoming weeks Slide 6 Bill of Materials Slide 7 Design Details - Wing Flying wing design: chosen because it is a simple design to build from scratch as opposed to a design with a fuselage. Large wing area allows for lots of lift and slow flight. Slight dihedral and swept back wings: increases stability of the aircraft. Slide 8 Slide 9 Slide 10 Design Details Control Commands Flying wing type aircraft use "elevons", which act as ailerons and elevators simultaneously rather than having independent ailerons and elevators This design is more efficient because it combines the two motions into one element Slide 11 Design Details Radio Commands Slide 12 Design Details Airfoil Asymetrical (cambered) airfoil Airfoil name: Sipkill Advantage: more lift at a horizontal position than a symmetrical airfoil Chosen because this needs to be a slow flying aircraft for surveillance. More lift = slower speed required for flight. Slide 13 Design Details - Propeller Propeller: front positioning, "puller" propeller The vehicle must take off and cannot be thrown, so a rear propeller location would exceed the constraints A rear propeller would contact the ground unless unwieldy landing gear was used to elevate the wing high off the ground Slide 14 Design Details - Material Frame constructed with balsa, covered with microlite vinyl iron-on covering Balsa is one of the best materials to use because of how light it is, which is important for a slow-flyer Slide 15 Design Details Landing Gear 3 wheels of a 3 inch diameter will be connected to the micro aerial vehicle to provide a safe and gradual landing onto the ground Slide 16 Design Details - Motor Connects to the propeller using rubber rings, making a motor mount unnecessary Slide 17 Slide 18 Design Details - Receiver Slide 19 Design Details - Battery Slide 20 In Conclusion We thank you for your attention to our presentation.
