The function of the propulsion system is to produce thrust, which is the force that moves a rocket through air and space. Different propulsion systems generate thrust in different ways, but always through some application of Newton’s third law of motion. In any propulsion system, a working fluid is accelerated …

The employment of UAVs by various industries and in Defense and Security missions are enabled by their propulsion system to provide them with the necessary power to propel the aircraft for forward flight or hover. Propulsion systems can advance the flight time or endurance of a UAV which is influenced …

Marine propulsion is the mechanism or system used to generate thrust to move a a naval vessel across water. At present, 90% of the sea-going naval ship are diesel-powered. There are numerous benefits to electric motor propulsion including that it’s quieter, more efficient at lower speeds and less smelly. It’s …
Read More »An optical network is a communication system that uses light signals, instead of electronic ones, to send information between two or more points. The points could be computers in an office, large urban centers or even nations in the global telecommunications system. These include limited range local-area networks (LAN) or wide-area …
Read More »Currently, most vehicles rely on internal combustion engines for locomotion; however, a significant shift toward partial and complete electrification is likely to emerge as an alternative propulsion system for vehicles. An internal combustion engine system is highly cost-effective and hence, its usage is higher than other propulsion systems. Being a …
Read More »One of the major lessons from Ukraine’s artillery war is that the side that can shoot farthest dominates the battlefield. According to the report, Russian howitzers are expending 20,000 shells daily on average, compared to 6,000 fired by Ukraine. The ratio for rocket artillery and ballistic-missile launches is even worse. …

The diode and the transistor introduced by Braun and Bardeen and Brattain are undoubtedly the corner stones of modern information technologies. Such devices allow for rectifying, switching, modulating, and even …

All Aircrafts depend on propulsion system is to produce thrust so as to lift the object for a prolonged period of time by consuming different fuels. Presently jet engines are the workhorses of airplanes carrying millions of people, trillions of miles every year, at supersonic speed and with high safety; …

Most spacecraft propulsion concepts can be classified into two categories: chemical and electric. Chemical propulsion relies on chemical reactions and can produce high thrust, but requires a large amount of fuel. Electric propulsion uses electromagnetic fields to accelerate ionized gases and is very fuel-efficient, but produces small amounts of thrust …

Energy is a critical enabling component of military operations and demand for it will continue to increase over time. In particular, energy usage during contingency operations will likely increase significantly over the next few decades. The modern operational space has amplified the need for alternative energy sources to enable mobility …
