Working principle:
System structure:
The goal:
Step 1:
Take off of a flying car can be performed by control or in
automatic mode. In the second case, human choose a
height by himself (from minimal, which depends on
construction, to maximal – 100 m).
Step 2.1:
(x1;y1;z1)
(x2;y2;z1)
(x3;y3;z1)
(x4;y4;z1)
On the Earth, along proposed airway, located communication centers.
Their coordinates set during installation, after what, they stay
unchanged. For airway creation, for the same distance set virtual
points. According to the axiom of geometry, every two points can be
connected, that the thing which the communication centers do.
Step 2.2:
(x1;y1; z1)
(x2;y2;z1)
(x3;y3;z1)
(x4;y4;z1)
Every communication center has its workzone. There is a special light on every car, where by communication
center finds out that there’s a new vehicle in his zone.
Firstable , after finding out, communication center finds coordinates of flying car.
This is done in such a way:
1) Building a coordinate system with the starting point in the communication center.
2) Knowing the coordinates of communication center and using coordinate system, there’re car’s coordinates.
Step 3: Compliance of s
(xа,ya, za)
(x1,y1, z1)
(x2;y2;z1)
h – is a safe distance.
Communication center calculates real
distance between the cars, using formula
|хb-xa|, and compares it with h. In the
case of an invalid rapprochement car, the
system automatically resets the speed of
the car behind.
h-?
(xb,yb, zb)
(x3;y3;z1)
(x4;y4;z1)
While the flying car moves on the airway, there're calculation of the safe distance between
him and the car in front of him and the desired result displays on the screen.
When the car reach the minimum safe distance, the person receives notification of this.
If the vehicle continues to pick up speed, the system automatically reduces the speed - as
long as the distance would be safe again.
Step 4:
There’s also an altimeter inside a car, which calculates
and shows a height of fly.
While driving on the "airway" car maintains a constant
height because her changing can cause an accident.
Step 5:
In emergency situations driver has opportunity to contact
with a dispatcher for the help.
Step 6:

А
(x; y; z)
A(x0; y0; z0)
B(x0; y0; z1)
C(xup; yup; z1)
If during the driving car needs to change the airway, then it’s following
algorithm:
1. Build a system of coordinates in three-dimensional space (x; y; z).
2. The system calculates coordinates of the projection of the vehicle (A).
Step 6:
B

(x; y; z)

Sbc=|xup-x1|
Sab=z1-z0
Sab

Sbc 𝑧1 − 𝑧0
=
t1=

V𝑐
3. The system calculates distance (Sbc) from the car #2 (image by point С) to projection of our
car (point B) and, also, height (Sab).
4. Using these data, the system calculates lifting time (t) of the car (A) and time (t1) when the
car will be at the same point.
5. If t = t1, then the system will beep to the driver, and will display a warning about the
impossibility of recovery and rebuilding the car.
Else: rebuilding the car is permitted.
Step 7:
Protecting of our systems from cyberattacks can be carried
out with the help of RSA or AES algorithms.
