PROPULSION OF ROCKET

-

 





The principle of rocket propulsion works on the 'Newton's Third Law of Motion'. 
It states that for every action, there is an equal and opposite reaction'. As far as the rocket is concerned, the engine of the rocket releases hot burning fuel in the downward direction

Rocket works on the principle of conservation of momentum. Rocket ejaculates gases in backward direction which creates momentum of the gases backwards and thus by conservation of momentum, the rocket gets momentum in the forward direction making it move forward.

when the rocket is released the pressure inside the body decreases as the speed increases and launches the rocket upwards

There are four major systems in a full scale rocket; 

 Structural system.

 Payload system.

 Guidance system.

 Propulsion system.

      Rocket Propulsion works on on the Principal of Law of Conservation of linear momentum
      P = Mass * Velocity
      and Newtons Third law of motion.

  Unmanned Power Sub Station System An Unmanned Power Substation System refers to a modern and technologically advanced electrical substation that operates without the need for constant on-site human presence. These unmanned substations utilize automation, remote monitoring, and control technologies to efficiently manage potential events. Automation and Remote Control The system is equipped with intelligent devices and sensors that automate various tasks such as monitoring voltage, current, temperature, and other parameters. Remote control capabilities allow operators to manage the substation from our command center. Reduced Operation and Maintenance Costs With the elimination of on-site personnel, the operational and maintenance costs associated with manned substations are significantly reduced. Routine maintenance tasks can be scheduled and monitored remotely. Enhanced Reliability and Safety The use of automated systems ensures greater reliability and minimizes the risk of human ...

Difference Between AC And DC Motor

  Difference Between AC And DC Motor The difference between AC and DC Motor are discussed below: AC Motor vs DC Motor AC Motor DC Motor AC motor runs on alternating current. DC motors operate on direct current. There is no need for conversion of current in AC motors. Like AC. There is no need for conversion of current in AC motors. Like AC. AC motors are used where power performance is demanded for extended periods of time. DC motors are used where the speed of the motor needs to be controlled externally. AC motors can be single-phase or three-phase. All DC motors are single phase. In an AC motor the armature does not rotate while the magnetic field keeps rotating continuously. In a DC motor, the armature rotates while the magnetic field rotates. Repairing AC motors is not expensive. DC motors are very expensive to repair. Brushes are not used in AC motor. Brushes are used in DC motor. AC motors have a very long life span DC motors do not have a very long life span. The speed of AC...

MOSFET

  What is MOSFET? The MOSFET, also known as a metal-oxide-semiconductor field-effect transistor, is a type of FET with an insulated gate that is assembled by the controlled oxidation of that  semiconductor . The semiconductor used in it is generally silicon. In more detail, we can explain that it is a four-a terminal-based device that is composed of a, Source(S) Gate (G) Drain (D) Body (B) In a general overview, the body of a MOSFET is in connection with its source terminal hence forming a three-terminal device such as a field-effect transistor. It is normally considered a transistor and is utilized in both digital circuits and analog circuits. A MOSFET can function in two ways Depletion Mode Enhancement Mode Enhanced Mode Enhanced mode can be defined as if there is no voltage across the gate terminal then the device will not conduct. But when there is a maximum voltage present across the gate terminal then the conductivity of the device gets enhanced. Depletion Mode Depletion...
