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

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 100’x50’x30’ 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.

Bill of Materials
![Page 7: ES 100 Micro Aerial Vehicle Group 1](https://reader033.fdocuments.in/reader033/viewer/2022051518/568163df550346895dd53981/html5/thumbnails/7.jpg)
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.

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

Design Details – Radio Commands

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.

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
![Page 14: ES 100 Micro Aerial Vehicle Group 1](https://reader033.fdocuments.in/reader033/viewer/2022051518/568163df550346895dd53981/html5/thumbnails/14.jpg)
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

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

Design Details - Motor
• Connects to the propeller using rubber rings, making a motor mount unnecessary
