Running time with full tank, 9 liters 9.5 seconds

Rocket propulsion - Aerospace Forum - Information Technology

Rocket propulsion is a sophisticated structure, its principle is mechanics, thermodynamics (Thermodynamics), as well as the use of other related sciences. Rocket thrust from Newton's third law (Newton's 3rd Law, action and reaction). Fuel through the combustion chamber (combustion chamber) after combustion, will produce high temperature and pressure of the gas, and then through a nozzle (nozzle) and the acceleration and exhaust to the outside world. These gases push the rocket is the driving force. Rocket classified in the following:

     Gas acceleration method (Gas Acceleration Mechanism)
     Sources of energy (Energy Source)
     Thrust (Thrust Level)

Gas acceleration method (Gas Acceleration Mechanism)

     Heat (Thermal) eg: Average fuel rocket (propellant rockets)
     ESD (Electrostatic) eg. Ion engine (ion thrusters)
     Electromagnet (Electromagnetic) eg. MPD engine (Magneto Plasma Dynamic Thruster

Sources of energy (Energy Source)

     Chemistry (Chemical)
     Solar (Solar)
     Nuclear (Nuclear)






Thrust (Thrust Level)

     High (> 1 G) eg. Rocket
     Low (<1 G) eg. Thrusters



Rocket Features

Rocket with the average aircraft engines the main difference is: Aircraft engines can only fly in the atmosphere, but the Rockets can work in outer space, because it does not promote the use of air will be able to burn. So it will not be highly affected thrust (thrust independent of altitudes). In addition, its thrust - weight ratio of (thrust - weight ratio) is high.

Usefulness of the rocket

     Non-space applications
         Missile propulsion systems (propulsion system for missiles)
         Supersonic aircraft propulsion system (primary propulsion system for supersonic research plane eg. X - series)
         Takeoff auxiliary propulsion system (Assist take-off rockets forairplanes)
         Escape Device (ejection of escape capsule)
     Rocket
         Soyuz
         Titan IV
         Space Shuttle
     Space Usage
         Transfer orbit (orbital change, plane change, trajectory transfer)
         Track maintenance (orbital control, orbital correction)
Chemical Rocket Engines 

Chemical rocket engine (Chemical Rocket Engines) can be divided into:

     Solid rocket motors (Solid Propellant Rocket Engines)
     Liquid rocket engine (Liquid Propellant Rocket Engines)
     Hybrid rocket engine (Hybrid Rocket Engines)

Solid and liquid rocket rocket rocket is now more commonly used. In addition, there is a hybrid rocket --- solid fuel (solid propellants) and a liquid oxidant (liquid oxidizer). Also worth mentioning is that, now contains the most liquid rocket launch vehicle with the solid rocket that is, a rocket will first (first stage) is solid and the second is liquid.
Solid Propellant Rocket Engines 

Solid rocket fuel (fuel) and an oxidant (oxidizer) is a solid state storage inside the rocket projectile. Solid fuel rocket engine is mounted directly on the rear of the rocket, when the use of lighter use (Ignitor) triggered fuel combustion, produce thrust push rockets.

Main components:

     Igniter (Ignitor)

     Housing (Casing)
     Nuclear fuel (Grain)
     Nozzle (Nozzle) 
Space Shuttle Solid Rocket Booster 

Liquid Propellant Rocket Engines 

 

Liquid rockets and solid rockets difference lies fuels. As the name implies, of course, is liquid rocket fuel in liquid form. The benefits of fluid which can be compressed (compressible), so the volume will be lower than the solid, the same density, the weight of the low. This is the liquid rocket reasons for the higher specific impulse.

Fuel properties

Liquid rocket fuel can be divided into storage and require special devices to save some time categories. Need a special device for the fuel pressurizing and cooling equipment necessary in maintaining the liquid state prior to combustion, such as LH2 and LOX. This type of liquid rocket fuel before launch will be entered into the rocket fuel tank (Fuel Tank).

Another type of fuel is in the general environment that exists in a liquid, does not require additional equipment to maintain. Early this type of fuel is highly corrosive and can not perennial storage, processing, or is in the process of transportation, safety measures need to prepare. Late liquid rocket fuels to be stored for long period of time the fuel tank, corrosion resistance is low. However, this is still a fuel storage life is certain, but significantly extended.

 Rocket Engine f1 3d model

High detail rocket engine loosely based on the Rocketdyne F1 of the Apollo era. I say loosely based as it is not an exact replica. Big model. Not much is optimized or attached so you can mess with it. Everything is attached to a dummy so sizing the dummy will scale the whole model. I included a rocket exhaust with shock diamonds for you to play with also. Download as a separate item. Use video post with blur fire.
