The Problem We are tasked with designing and building a micro aerial vehicle (MAV) that is competition legal for the European Micro Air Vehicle Conference and Flight Competition. We are tasked with designing and building a micro aerial vehicle (MAV) that is competition legal for the European Micro Air Vehicle Conference and Flight Competition.
Project Scope and Needs Products of Project RisksBenefits 10 minute flight time Battery Life and weight of components. Longer flight time the more tasks can be achieved. Fly at least 5 m high Failing from 5 m high would be destructive. Ability to hover over a building. Fly at least a distance of 50 m Transmitter losing contact. Can achieve more tasks. Display the 6-DOF in the air Losing control of the MAV and not being able to recover More maneuverability. MAV within size specifications (lateral of 70 cm) Weaker components with smaller size. Can enter into smaller spaces. Carry at least one camera and transmitter Cameras may be heavy and or costly. Ability to identify targets and receive more information. Weight less than 1 kg Too light to stand up to any wind, also may not be strong enough (weak points) Easier to carry and requires less lift to get off the ground. Operation by one person Inexperienced pilot may destroy MAV Ease of use, requires only one person to fly. Hover for 10 seconds None Ability to take stationary footage
Original Design –2 Flapping Wings –Controlled rotation of the wings –The wings use a track to slide back and forth –DC Motor rotating causes the wings to flap
DelFly Inspired –2 sets of wings in an collapsing/expanding x formation in an up and down movement –Ruddervator –Very small and compact
Blimp Rotary - Blimp filled with hydrogen - Flapping wing control system or rotary - Dual Wing, counter rotating helicopter - Very precise hovering - Small
Dragon Fly Inspired –2 sets of wings in an collapsing/expanding x formation in an up and down movement –Tail rotor –DC Motor rotating –A larger toy
Dual Flapping Wing Rotary and Flapping Symbiosis - Dual flapping wings that flap in contrary horizontal flapping motions - Tail rotor to control yaw - Set of flapping wing for forward propulsion - Rotary wings for lift - Would require a tail rotor
Bird Bat - Actuated joints in all directions that cause the wings to curve in aiding to the flight - Fast flapping - More fixed wing then bird but jointed

Design Chosen The Delfly inspired design was chosen as our flapping wing MAV because of its ability to meet our customers needs and has the highest probability to fulfill our design criteria and complete all necessary functions.
Immediate Future Plans Complete Budget Layout of materials. Complete Budget Layout of materials. Detailed design drawings. Detailed design drawings. Pro-E model of product. Pro-E model of product. Various testing for best possible design/materials (ex: wind tunnel, wing strength vs weight) Various testing for best possible design/materials (ex: wind tunnel, wing strength vs weight) Begin purchasing materials.
