Moonshot #2 : Brief Explanation Of Solid-Propellant Rocket [Part 2]
Solid-Propellant Rocket.
When loading the propellant into the rocket we don't dump entire fuel into the rocket's motor case and light it on fire, there is a proper way to do that which is to load the propellant in pattern , and we call it the Grain Geometry.
Solid Propellant Rocket Components [*1]
When loaded in patterns not only we able to determine the thrust the rocket will be produced but also the burn time and burning rate of propellant. With variety of patterns that can create different kind of burn, each one should be suitable for varied missions.
Nozzle is designed to accelerate hot exhaust to produce thrust meaning the nozzle is there to increase the velocity. Nozzle usually made of graphite, reinforced carbon-carbon, tungsten-molybdenum alloy, and other combination of metal such as niobium copper tungsten graphite and aluminium because it need to withstand heat as hot as ~3000°C ( ~5400°F or ~3300°K ) not to mention the great amount of pressure exert on the nozzle.

Rocket's Avionic Systems is the most important part of the rocket. it does everything from navigating, communicating, sensing, controlling, guiding, steering ... everything that make it flies smoothly.

Most of the time when one these systems malfunction the flight is very likely to failed and rocket generally would disintegrated during flight.
That's all for today folks Thanks You so much for supporting and don't forget to upvote and comment down below. If you've seen any errors and misconceptions just let me know :D
Stay Tuned For More.
Ps : Because of the length of the paragraph i decide to split it into two parts.
