The codes will be uploaded soon...

In this project, a ballistic missile simulation physics will be implemented in unity environment. The physics system written from scratch.

Project content:

1-2-4 missile propulsion system and rocket orientation control
The effect of the wind on the missile
The effect of air density on the missile
External control of the missile by phone
Fuel tank location and filling (center of mass)
Display systems (fuel, flight control, flight time, etc.)

General Structure of Ballistic Missiles: Ballistic missiles usually consist of one, two or three parts. Each Compartment also contains its own engine and fuel. The first piece at the back pushes the missile until it runs out of fuel, and leaves the system when it runs out of fuel. Afterwards, the missile continues to be pushed by using the inner engine and fuel. Thus, when this compartment runs out of fuel, the missile goes into free slanting motion. It is aimed to hit the targeted point by following its trajectory.

Simulating the Wind:

Fw = 1/2.p.V^2.A Fw : wind force at specific point (N) A : surface area (m^2) p : density of air (kg/m^3) v : wind speed (m/s)

Simulating Air Density

Air density depends on these: Density of dry air -> p = Pa/(R*T)
p : density of dry air R : specific gas constant for dry air T : Temperature Pa : Pressure

Thrust System

In the increasing of the missile speed, total mass, exhaust velocity, mass flow rate and also external forces like gravity, and air resistance play role.
