The document discusses the design of a hybrid drone capable of vertical takeoff and landing and operating on land, water, and air. A team is developing a transformable hybrid vehicle that can change configurations to perform missions requiring operations in the air, on water, and on land. This will allow a single drone to be used for multi-terrain missions, improving efficiency by reducing payload size, initial costs, and completion times. The team aims to build a compact drone that can function as a multicopter in air, hovercraft on water, and 4x4 vehicle on land through controlled transformation of its configuration.

INTRODUCTION
 Drone is any unmanned aircraft or ship that is guided
remotely without any human presence on board or beyond line
of sight. Yes! That’s areal drone note those annoying you in
marriages and parties .
 Three are basically 3 types of drones – Flying drones, Ground
drones & Water drone and are used in applications like search
and rescue , security inspection, surveillance, science &
research, aerial photography & video, surveying & gps
(mapping), unmanned cargo system etc…. Gosh they are every
where ……..
 The main problem face in traditional drone is that it restricts
the use of a drone to its particular terrains i.e. an aerial drone
cannot be used for water or land mission, the same happen with
other type of drones.
 Our team over team is working on the hybrid drone that can
cover all Three respective terrains it is going to be a
transformable hybrid vehicle which will be able to transform
itself from one face to another . This will allow the user to carry
a single drone for a mission which includes air, water and land
task. The drone will improve the mission timing reduce the
carrying load and space, decrease the initial cost and ultimately
increases the feasibility of mission….. Woahhhh its coming !!
What We Talented Personalities Aim For …..
So the main aim of the project is to Design and build…
 yes we are going to built it.. A compact hybrid of a flying multicopter
which soars through the sky, a hovercrafts which floats over water like a
swan and a 4x4 off-road buggy with jump and crawl over rocks &pebbles
like it’s a piece of cake
Major challenges would come in designing phase as its crucial to make
a rigid plate form which would be able to with stand the torque and
gyroscopic effect produced by the rotors .
Next challenges would be to obtained the lightest and strongest
materials like carbon fibre and Kevlar composites for the original build .
The expected result is an approx. 1100grms in weight and 3ftx2ftx1ft in
dimension hybrid drone, consisting for brushless dc motors running on high
frequency electronic speed controller via a high density lithium polymer battery.
The drone would be able to run smoothly on surfaces like sand, mud, grass,
shallow water. And with a flick of a switch the initial drone will transforms its
configuration from that of a hovercraft to a quad copter with the help of controlled
digital servos .then the drone will act as a quad copter and achieve its flight with
the help of four horizontal propellers thrust up to a certain height. The controls
will be assisted by a six axis controller board during land areal flight.
The final outcome will be a compact all terrains drone solution for a soldiers,
army personnel’s etc. which is cost and space effective and can achieve high
degrees of surveillance capabilities further it can be mounted with infrared or heat
seking cameras .
The magic of lift, drag, up thrust, rotating big propellers, aerofoils, high-tech very
expensive out of the budget lithium polymer batters, cheap thermocol to fill-up the space
because we cannot stuff money there. And yes!!!Some American accent YouTube video …
to clear our very basic concept of ’’how airplane fly’s’’,’’ how to make a hovercraft’’ and
yes we will add ‘’ at home is less budget’’ in every search… ;(
The main designing will revolve around the structure of a typical hovercraft where one
system fills up the plenum chamber which allows it to lift just above the ground making it
frictionless…only 2-3inches above for a full size hovercraft, the second system propels
and steers the hovercraft forward and in directions
 In our hybrid the model will cover the land and water terrains like a typical hovercraft,
while for flying the lifting system consisting two rotating propellers will shift outside the
body horizontally and the forward propulsion system will turn 90 degree and come in line
horizontally with the first making a quardcopter configuration for the flight …hurray!!!
