Viscoelastic materials such as pressure sensitive adhesives are used as constrained damping layers in a variety of applications. Historically, materials such as foams and acrylic and rubber adhesives have been popular choices. However, in the aerospace and defense markets, innovation is occurring at a rapid pace. For example,
The Light Airship concept is an innovative relaunch of the Dirigible/Airship technology retrofitted with cutting edge modern technology to make it very reliable and the most eco-friendly mode of transport. The main objective of the Airship is Urban-mobility in the world where the cities are facing increasing traffic congestions day by day. As reports predict,
INTRODUCTION
The maturity of the technologies for the guidance and control of UASs allows proposing innovative operational options such as the ability to spray a significant amount of an agent of any sort at a pre-established point in the atmosphere.
This is the case of NitroFirex,
In order for a jet engine to become multistage it must have a multistage afterburner or a multistage combustor. In order for a combustor to become multistage it must actually operate through the combination of uninterrupted and pulsating combustion. Uninterrupted combustion in stage 1 and pulsating combustion in higher stages through pulsating fuel feed.
Firearms are very dangerous and I hope you don’t have to use them in your lifetime but history has taught us that people always find a reason to go to war to the end of time. This project is neither promoting firearm use nor discouraging it but protecting the environment whenever/ wherever/ however you use it.
The objective of this research is to design and analyze a semi-tangential ogive bullet using computer-aided design & Computational Fluid Dynamics. There has been a quite steady increase in the research of bullet design in the past few decades. The design of the nose is the most important part of the design of a ballistic bullet.
A semi-tokamak geometry as shown in the accompanying illustrations forms a current carrying magnetized plasma loop. The current is generated either by means of induction or DC biased electrodes or a combination of both.
The Ring
An optimized spaceship for the 21st century
Up to now spaceships were conditioned by missile shapes, with multistage launchers and relatively small payload capability conditioned by the cylindrical fairing dimensions. Such conditions could be drastically changed by a proposed new vehicle with a different shape: the ring.
This is a concept for a new type of gas turbine engine that was designed for turbo electric power generation for hybrid aircraft, ie commercial airliners. The main idea was to reduce the cost, complexity and maintenance requirements of traditional gas turbine engine while drastically improving fuel efficiency and emissions reduction.
Orbiter mid deck is circular. Its floor has a spheric section curve of very large radius, as if it were a piece of a giant sphere hundreds of feet in diameter. Its imaginary center of revolution is hundreds of feet above.
Deck revolves, rather than rotate as in earlier concepts for artificial gravity spacecraft.
