Concept Spaceship With Inertial Drive

The concept of an inertial propulsion spacecraft was developed in response to the limitations of propulsion in the form of low- or high-temperature plasma recoil in current rocket propulsion systems. These limitations mean that the rocket can only achieve a speed that does not exceed the speed of the plasma's ejection from the engine nozzle.

How a Toothpaste-like Gel Revived Bullet Proof Vests: a Win-win Solution

Aramid fibers are very effective for ballistic protection systems, particularly bullet proof vests. When aramid fibers are compared to steel, on an equal-weight basis, its strength is five times higher than steel. Due to natural degradation and security issues, these bullet proof vests must be replaced by new ones every five years.

Plasma Solid-State Engine

Introduction/ Inspiration: Laser-induced breakdown spectroscopy (LIBS) uses a high intensity laser pulsed for ns (nanoseconds) to form a plasma and atomize a local point on a material sample. When the laser is discharged it ablates a very small amount of material, in the range of nanograms to picograms,

Prevent Flood by Crossing Sea Guard Wall of Sea Wave

It is seen at the time of a cyclone that the wave of sea is crossing the guard wall and creating a flood. To prevent a flood from this reason the height of the sea guard wall must be increased. But if we do increase the height of the sea guard wall of bricks or concrete permanently,

Low-cost Propulsion Method for Target Drones and Related Equipment

From WW II and later, also from its use as rotor tip power in some helicopters, we know Ramjets could have a use in certain applications where fuel economy is not first requirement. German data seized by the UK indicate Lorin Ramjet best arrangement is 10º divergency in the intake/ diffuser section, for a total length of 1559 cm,
