Transport is responsible for around 23% of energy-related carbon dioxide emissions globally. This is expected to double by 2050. 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 …

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 …

Stealth technology has proven to be one of the effective approaches to enhance the survivability of Aircrafts. Aircraft/helicopter designers are making them stealthier by reducing their signatures; viz. visual, aural, infrared (IR), and RADAR cross section. Advancements in stealth technologies, as demonstrated by the very low RCS of stealth aircraft …
