A rocket is defined as a technologically advanced reaction motor that can carry its oxidant to propel a launch vehicle. A reaction motor is used as a propulsion device to generate a forward push by expelling the rocket structure in…
A transducer is any device used to convert energy from one form to another, such as a conversion from mechanical to electrical energy or vice versa. An electroacoustic transducer is a device that converts acoustic energy (sound) into electrical energy…
A stealth ship is a type of ship which is especially used as a war vessel and is concealed from the navy vessels of other countries. It is an important warfare tactic that is used by nations wide across the…
Generally, materials will degrade over time due to fatigue, environmental conditions, or damage incurred during operation. Repair of certain materials during their lifecycle (especially those with structural functions such as concrete) can be very expensive and labour intensive. Therefore Scientists…
3D printing or additive manufacturing is ongoing revolution in manufacturing with its potential to fabricate any complex object and is being utilized from aerospace components to human organs, textiles, metals, buildings and even food. 3D printing is also revolutionizing defence…
It is estimated that around four billion people on the globe suffer from water scarcity. Distribution and production of fresh water and the control over water sources are potential cause for conflicts. Therefore, researchers are investigating new ways of freshwater…
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…
Integrated circuits and power devices utilized by the semiconductor industry for the production of advanced computers, consumer electronics, communication networks, and industrial and military systems have been almost exclusively based on silicon technology. The requirements of future electronics place a…
The jet engine is the most complex element of an aircraft and one of the most complex human-made products ever developed, housing thousands of individual components — and ultimately determining fuel efficiency for aircraft All turbines operate on similar…
In 2018, The American Society of Mechanical Engineers (ASME) named the Pratt & Whitney single crystal turbine blade an historic mechanical engineering landmark. These blades, which can be found in many modern, high-performance gas turbines (a.k.a. jet engines)—including the ones powering…
