Non-destructive testing (NDT) is a way to detect and evaluate flaws in materials. The simplest and most accurate way of testing materials and components is often to test them to destruction. Destructive testing is used in aerospace to determine the physical properties of materials, components and assemblies. It can reveal …

The US’s  GBU-43/B Massive Ordnance Air Blast (MOAB) is a precision-guided munition weighing 21,500 pounds and was dropped from a C-130 Hercules aircraft. The MOAB isn’t the heaviest non-nuclear bomb in the US arsenal (that’s the 30,000-pound Massive Ordinance Penetrator ), but with a length of 30 feet and an …

Magneto resistor is a type of resistor whose resistance changes when an external magnetic field is applied. In other words, the flow of electric current through the magneto resistor changes when an external magnetic field is applied to it.   Magnetic field is the region present around a magnetic object …

Man-Portable Air Defense Systems (MANPADS) are surface-to-air missiles that can be carried and fired by a single individual or carried by several individuals and fired by more than one person acting as a crew. MANPADS were designed to be used by national military forces to protect their troops and facilities.
