Overview for A-00

Throughout my life I have been fascinated by airplanes, hours and hours in flight simulators the PC and my curiosity allowed me to go venture this world. But what most excites me of the airplanes is the power  and freedom   they can achieve this machines, as soaring in the sky many tons, It is something magical and surreal, my dream is to be a pilot to fly ever some of these machines. The world of aviation is very extensive exciting, there are planes of all sizes, shapes and color, each is marked on the essence of people who have worked and dreamed to bring this magic to this world, my inspiration comes from them, of all this people who contributed little or much of themselves to bring the reality of this world the dream of flying.

"To fly very high in the sky, must be well placed the feets in the ground"


Explanation of design details

It is a simple and austere design, I used existing aviation technologies, which have been tested and they are reliable, in that vein, my design proposal aims to encompass certain important points. The first is the aerodynamic wing, based on the principle of flight, where the air flows faster at the top, that below, creating a stream of low and high pressure, therefore did remove all objects or elements above the wing that could affect this principle and place them in the area of high pressure below the wing.  The next point, the dimensions of the wings, if it is larger, the airplane will be more sustainable in flight, finally, in order to reduce the weight and number of parts, I decided to use tail-V and materials textile to cover both surfaces, obtaining aerodynamic characteristics similar to other airplanes known today, also I did to an friendly image (non-hostile), this due to emergencies and disasters, where the airplane must work.

Motorization:Engines use four vertical takeoff and landing (VTOL) and a motor in the stern for   conventional flight.

Details:

Four motors made to measure which they are among the 170 KV and 192 KV with an average weight of 400 g each reduce weight using similar technologies to T-Motors.

Battery:  

Where they will be located

On the sides of the frame near the wings are the  batteries pods , this location provides easy and quick access for fast operation, will not load any weight on the wing, serves as a reinforcement of the wing, complemented by titanium wires avoiding the use of screws or rivets.

Each battery is placed in a cartridge changeable, supports 3 batterys 6s 16000mha, The cartridge  fits in a pod in the frame near the wings.

Details:

Configuration A:  Operating range up to 100 km, with a load of 3 kg.

              6 battery 6S 16000mAh NO Flight Termination Parachute.

              Important, the battery must be full charge and discharge will be 100%

Note: The operating range of 100 km with 3kg can be achieved at flight altitudes above 300 ft otherwise it is essential to favorable climatic conditions, such as tailwind, humidity, temperature during cruise flight.

Configruation B: Operating  range up to 60 km, with a load of 5 kg.

4 battery 6S 16000mAh

Normal charge and discharge will be 85%

Landing gear

A landing gear tall, long, thin to decrease the weight and drag, increase the space for maneuver during the loading,  and  unloading , It works as an anchor point for reinforcing the frame of motorization avoiding structural deformation during takeoff and landing VTOL.

Allows conventional flight operations during landings and takeoffs, or in case of failure during vertical  landing or takeoff. 

Details:

Tires, brakes and landing lights led line titanium reinforcement frame.

“Waterproofness”

Both carbon fiber as PET are excellent insulators and

a protection from weather external, the polyester textile and  polyamide with which is cover the wing surface is waterproof and prevents the formation of ice likewise the  high sliding coefficient of both materials reduces the presence of ice.

Elasticity, chemical resistance, heat resistance, wear resistance and corrosion, do ideal materials.

The container and cargo: They are protected by the carbon fiber frame, covered by PET, being isolated weather and    extreme outdoor temperatures.

Motors: Waterproof engines using technologies similar to T-Motors

Batteries: Placed in carbon fiber pods on the sides of the frame near the wings, are isolated from the rain and extreme weather.


Modularity/Ship-ability

The modularity allows you to configure the aircraft for conventional flights.

It can be disassembled into parts up to 16 modules depending on the needs of transportation (van, vessel, aircraft, truck, ISO Containers).

Up to two people can accomplish this task easily, the dimensions of each of the modules 16 is less than 200 cm.

Assembly

Each piece it has marked with a color and a number, both pieces with the same color must fit, and numbering indicates the sequence of assembly.

When fitting each module, It should be locked screwing  joints  counterclockwise to clockwise until it is aligned with the marking  color  of module to be joined, it is important to do this, because ensures  feedings  of electrical  component (motors, lights, spoilers, etc.), and keep fixed parts of the aircraft, some parts joints  do not require screwing.

Finally, the structure is reinforced with titanium lines, are hooked to fuselage and landing gear.

After completion of the assembly can be started with voice commands, the computer will initiate a check that each component this properly connected before takeoff.

Ease of handling

The ability to modular configuration allows removing parts of the aircraft, and take advantage of its functionality, for example  a person can disassemble and carry only the wings, while the other  carry the landing gear pushing  the other modules over the.

Fail Safe components to prevent catastrophic failure

In case of a failure in the motors vertical takeoff and landing, the aircraft can carry a conventional landing.

In the event of a structural failure in a configuration for flights less of 60 km, has parachute system.

The worst case scenario would be a fire in the batteries, there is no way to recover the aircraft and dispose of defective components during flight without  endangering  to people in ground.

Safety provisions:  Limit time on ground with rotors spinning

In ground, the computer through the camera, scans people or animals approaching, for safety they turn off motors and only turn on, when receiving the command voice, "Clear for takeoff".

Countering vibrations

The vibrations caused by the engine are absorbed by pads arranged in the joints attached to the motors.

Vibrations caused by turbulence, winds and other weather factors.

Lines titanium and carbon fiber frame are resisting these tensions, the properties of both materials make them ideal for this work.

Offsetting the drag

It was conceived design wing  a larger surface to counter the drag caused by the landing gear, engines, and components propeller.

The biggest challenge was the weight.  Was solved using the techniques of ultra light aircraft, using textile fabric high strength (polyester textile and polyamide) as a coating for the wings and tail in V.

An tubular carbon fiber frame where this the electrical wiring inside  and lines of titanium provided rigidity  on each wing.

Carbon fiber frame details:

Diameter  3 cm to 5 cm

Thickness 1 mm.    

Bay load

Made PET de 0.8 mm Thickness 

Payload and Cargo concept 

Interior dimensions along with provisions for securing cargo

Located in the middle of the airplane, is payload bay, accessible from the lower side of the aircraft it must be given commands in voice (Payload bay open) to open and go down a basket where the cargo container is placed.

Payload bay dimension: 450 x 350 x 200 mm

The operator manipulates the load should push up the basket, if the load and the state of the container are within established safety parameters, the basket will remain up to again give voice commands, otherwise the basket  stays down until parameters are met. If the payload bay not completely closed the aircraft does not fly and motors will remain off until solve this. 

Each container is made of expanded polystyrene (EPS) in its bottom has moldings it fit into the basket, which prevents sliding during flight.

The container has a RFID ( Radio Frequency IDentification) which is scanned by a reader located in the load hold, if not RFID corresponding or not detected, the load is not accepted.

Configurability concept to change from cargo to sensor payload

The RFID Send the following information to the computer of the aircraft: type container, vacuum container weight and speed of data transmission.

There are 4 types of containers, large (L), médium(M), small(S), very small(VS)

The plane can load up to 2 (VS) containers.

Once the operator loading the container, place it on  basket and pushes up, the basket  remain in that position if the following parameters are met

1.- The time  traveling RFID signal, is the position of both the container lid, in relation to the type container (L, M S, VS), its position in the basket and if this  well closed

Moldings which fit in the basket, facilitate proper positioning of the container.

2.- The weight sensor in basket determines if net 5kg are exceeded in relation to the type of container (L, M, S, VS), depending on the flight to do, the computer will request the appropriate configuration of the aircraft, that is: Battery configuration , without or  with parachute, this is defined remotely

Basket

The mechanism of ascent, descent and lock system basket consists of a set of plastic pistons, air passes from a cavity to another forming an air mattress.

when the instruction  in voice is heard , an electronic lock system safe disengages the basket , gravitational attraction descends gently the basket , the operator must load and push up the basket, it automatically lock  if met safety parameters, after the   operator away, gives voice commands(Clear for Takeoff )
