The solar cells produce electrical power (current) from incident sunlight. However, individual solar cells generate very little power. So, in order to generate more power, a group of cells that are present in an array form can be used. Solar arrays are primarily used in satellites in order to provide …

Virtually every modern naval weapons system, in fulfilling its mission, is highly dependent upon the performance characteristics of its electrochemical power supply. For example, batteries are used to power detection, guidance, control, ignition, propulsion, arming, fuzing, transmitting and jamming devices. The need for weapons with increased range, speed, endurance, sensitivity …

All the satellites require internal power in order to operate various electronic systems and communications payloads that are present in it. The Electrical Power System (EPS) is a vital subsystem whose primary role is to supply satellite …

Motor vehicles also put a burden on society, especially in urban environments where they are chiefly responsible for noise and air pollution. Electric vehicles (EVs) have been considered as critical technology for …
Read More »Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidizer, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engines, rocket engines are the lightest and have the highest …

A new power revolution is going on in orbit – that of electrical propulsion for satellites. An ion thruster is a form of electric propulsion used for spacecraft propulsion. It creates thrust by accelerating ions with electricity. As the ionised particles escape from the aircraft, they generate a force moving …
