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

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

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

Design Details - Receiver

Design Details - Battery
