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.

    Sir What is the formula for rocket propulsion problems?

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

Alternating Current

  What Is Alternating Current? An  alternating current  can be defined as a current that changes its magnitude and polarity at regular intervals of time. It can also be defined as an electrical current that repeatedly changes or reverses its direction opposite to that of Direct Current or DC, which always flows in a single direction as shown below From the graph, we can see that the charged particles in AC tend to start moving from zero. It increases to a maximum and then decreases back to zero completing one positive cycle. The particles then reverse their direction and reach the maximum in the opposite direction after which AC again returns to the original value completing a negative cycle. The same cycle is repeated again and again. Alternating currents are also accompanied usually by alternating voltages. Besides, alternating current is also easily transformed from a higher voltage level to a lower voltage level.

SOLAR TRANSFORMERS

  The transformers required for wind power and solar DPV require special design features to meet the challenging operating conditions. The industry today has developed different types of transformers for the application. The last few decades have seen very rapid development of renewable energy, especially, distributed photovoltaic (DPV) and wind power. It is estimated that at least 40 per cent of electricity generation by year 2040 would be from renewable energy sources and this would give appreciable reduction of the present level of carbon dioxide emissions of about 10 billion tons per year. The transformer industry is rising to this challenge and has developed special transformers for the DPV generation and wind generation. Transformers are critical components in solar energy production and distribution. Historically, transformers have ‘stepped-up’ or ‘stepped-down’ energy from non-renewable sources. There are different types of solar transformers including distribution, station, su
