1. The flaps and the wings icingI have noticed the aggressive effect of ice all over the world. In our

case, ice is formed on unprotected areas of aircraft, such as front edges of wings, empennage, horizontal stabilizers or also engine air intakes, such as flying aircraft through clouds that contain overcooled water droplets or moisture. With the growth of a layer of ice, the latter adversely affects the flow of air along the corresponding surface. When the layer becomes large enough, there may be problems, for example: problems with the carrying capacity and control of the aircraft.

Proposal and solution of problems.We propose to use rubber as a

coating for aircraft in areas that are subject to most of the icing. In order for ice not to be on rubber for a long time, we use vibrational waves. When vibrating on rubber, the ice crust will fly off instantly. Vibration on the trim of the aircraft rubber will absorb and not harm the aircraft trim. That will improve the durability and strength of

the aircraft. To create artificial vibrations of the wing or plane empennage, a cylinder is used in the device, provided with grooves to control the mutual arrangement of loads that create an imbalance when the rods of the rods passing through the slots of the cylinder rotate freely on its shaft. The device is shown in the drawing.

2. Celestial interference from birds.  A bird strike (sometimes called bird strike, bird hit, or BASH Bird Aircraft Strike Hazard) is a collision between an airborne animal (usually a bird or bat) and the aircraft. Bird strikes are a significant threat to flight safety, and have caused a number of accidents with human casualties. Major accidents involving civil aircraft are quite low and it has been estimated that there is only about 1 accident resulting in human death in one billion flying hours. According to data for 2017, out of 72 cases, 10 ended with damage to aircraft and 19 delayed departures. The total amount spent on repairs in 2017 amounted to more than 850 thousand dollars. In 2018, there were 37 cases of collisions of Air Astana’s birds with birds. Eight cases have occurred in Almaty since the beginning of the year.

Proposal and solution of problemsWe decided to use ultrasound on the aircraft itself, thereby not harming birds and the

environment, reducing the death of birds. I am bringing to your attention the Quadblaster QB 4 ultrasonic bird repeller. The protected area is 600 m² and the area diameter is about 28 meters. It can be charged from any modern battery. Given the low weight and the affected area, we chose two of the most effective points on the plane for maximum usefulness of this equipment. First, you can see the point between the wing and the fuselage. Exploring the device and experimenting with the design of the aircraft, we

decided that this point is effective due to the fact that it does not replace important places with itself and ensures its own mechanical safety. And from the minuses - here waves can be badly transmitted through the metal case and the radius of the affected area is too small for this point. Also here you can clearly see all constructive parts and components of this The second point on the front fuselage. Efficiency is in the full use of the affected area up to 14 meters birds can accurately fly away from the trajectory of the aircraft and easy control of the device by the crew. And what about the price - for medium-haul aircraft it will pay back all the damage caused to the environment and to the aircraft. Avoiding problems with animals inside the aircraft ,also we decided to control the device through a kind of remote control. 

3. The deformation of the aircraftMany planes come out of exploitation for long flights, which

causes deformation or corrosion of metal structures.For more efficiency of our project, we looked at the

possibilities of 3 D printing, types of efficient alloys. If we look at the stand, we will see 3 layers of reinforcement. Where we put in the first place Carbon. Which serves as a coated material for a stronger construction. Tantalum serves as the second: solid durable metal of silver color, at ordinary temperature shows little activity, acidifies at 280 ° C, and melts only at almost 3300 Kelvin. The third layer of Microlattice light metal, which is 99.9% air. In this way, we will improve the strength of the aircraft, the capacity of the passengers and increase the fuel economy during flight.

4. Fire extinguishingFor fire extinguishing, we use Novec 1230 Fire Protection Fluid - this is a new

generation tool that provides a large safety margin and excellent environmental performance.- Zero Ozone Depletion Potential- Life time in the atmosphere - 5 days- Global Warming Potential equally 1- A large safety margin for areas occupied by

people.It is used as a gas, but at room temperature it is a

liquid. The boiling point is 49.2 ° C, which means that this product has a much lower vapor pressure than other pure reagents, has a very low evaporation heat, about 25 times less than that of water. Does not conduct electricity.

Where you can see on the stand and see the tanks under the wing.The second method is to use Novec as spray, when fuel tanks are

damaged, at the same time with discarding the tank for not to cause environment with harm.

5. Rescue capsuleTo the conclusion we want to consolidate the material so that we offer a reusable

rescue capsule with little damage to the airlines. After reviewing a lot of reports and conclusions we propose to create a device that will serve as a capsule as well as a plane.

If the plane has an emergency situation and cannot be solved by any technology, examples of which are given above. At the same time the plane will start to fall and burn. Our idea is to create a plane that will drop wings thereby automatically launch part of the parachute lines which will be located near the tail of the aircraft and also replace wings. They will serve as a brake part to reduce the speed of an airliner.

After landing on any surface, liquid or solid, airlock are activated below the capsule, triggers the eject mechanism that triggers the airbag system.

This design will increase passengers survival rate, will also give the opportunity to apply this design several times, therefore increasing safety and efficiency due to reusability.

All these functions will be activated depending on the situation and the last word will be for the commander of the crew.
