Repair and integration in aerospace composite structure is highly demanding, however many complex processes are required to be performed, maintaining a strict process control and considering the stringent regulatory framework. Several stages are considered in the automated facility designed at Cranfield University with a group of six MSc students, two academic staffs and one research associate: inspection, material removal, surface preparation, repair patch design, manufacturing and integration, and post-repair inspection all automated in less than two hours. A number of state-of-the-art technologies, developed in high technology readiness level, have been combined in a cost effective way to guarantee a ...
Reaction wheels (RWs) are not only the standard solution for attitude control of conventional spacecraft such as telecommunication satellites, but they are also frequently used in smaller satellites with demanding attitude control requirements. Due to their simplicity and compactness, ball bearings are commonly utilized for mounting RWs, especially in smaller satellites. However, ball bearings have several disadvantages. For instance, mechanical friction and wear limit the reliability and lifetime. Moreover, RWs with ball bearings are usually operated in a hermetically sealed atmosphere for preventing the outgassing of the bearing lubricant, which adds to the weight, cost and the complexity of ...

Education, military, agriculture among other fields are using drones to benefit the proficiency. Drones are used in almost all the operations as well as the industries nowadays because of their reliability, cost effectiveness and multifunctionality.
Jet packs are similar to drones because they are propelled into the air as a result of escaping gases/fluids. The hydro jet pack has been successfully designed and developed and used in various applications. Water Jet Fire Extinguisher system uses water jet as the propulsion system as well as a fire extinguishing agent.
Water Jet Fire Extinguisher is a type of hybrid drone that ...
About My Project :-
The war against terrorism is on the rise and many such things are arising in most countries of the world. Only sleeper cells (name of our project) can change the tide of war in favor of user. It’s not like a traditional bombing, it’s much more than that because it will increase the accuracy of bombing in difficult terrains such as terrorist hideouts, attacks on bunkers in wars, and many more such hectic situations. It has a unique ability of hiding in any surroundings because of its camouflage for surprise attacks. It has a dual mode ...
This machine is based on gravity and potential energy formula. As per the sketch a heavy weight will be attached with a scale and a pulley + generator will work as a input source. Though the energy generated by this system will not be sufficient so an initial input will work to start the device.
A spring based generator under the front load will work to generate energy by compressing and stretching the spring and a piston based generator will also work to generate energy, when the tail of scale will hit with it. We can also use a MECHANICAL ...
The Compact Personal Aircraft or CPA (Patent Pending) is the embodiment of the future Air-Taxi. A novel improvement over its ancestor the co-planar multi-copter, the CPA may achieve up to a five fold increase in both flight time and fuel economy during horizontal, non-hover flight maneuvers. The observation that much of a typical helicopter's flight time is spent in the horizontal velocity flight maneuver, is self evident. The CPA architecture combines both VTOL capability of the helicopter with high fuel efficiency of fixed-wing aircraft, together in a compact planar area footprint.
Consider the high mechanical complexity of ...
"Hanger" is a conceptual aircraft as seen in the enclosed drawing. It doesn't have wings to lift. Instead, we have two propellers.
One is the aspirating propeller at about the middle and the second one is at the tail which is a viper propeller.
Hanger Aircraft has two jet engines, one for the viper propeller at the tail and the other one for the aspirating propeller.
Propellers blow the over passing air down into the jet engines compressor inlet. Air aspiration in turn is aimed to provide necessary lift for the aircraft. Jet engines are placed ...

In physics, pulsating combustion of gases from two or more different locations near each other will tend to push each away from the other and the resulting velocity of pulsating combusted gases are amplified by the velocity of combusted gases from the other pulsating combustion that are pushing them away. But the case is different in two or more uninterrupted combustions arranged in a linear position (as in the case of jet engines). In jet engines where linear combustion occurs, two or more uninterrupted linear combustions from different locations near each other creates a constant barrier between them, so ...

The proposed concept of a RF pumping source embedded into a resonant RF cavity of the resonant cavity thruster (EM Drive), consisting of a cylindrical tube and a frustum coupled together, assumes to use the cylindrical copper tube coupled with the smaller-diameter side of the main copper frustum as a body (cathode) of an inverted coaxial magnetron.
The proposed concept assumes that the inner surface of the copper tube will be covered by an electron emitting substance, such as carbon nanotubes (CNT) for instance, and used as a cathode of an inverted magnetron, while the multi-cavity anode of the ...
