The use of a building or civil engineering structure may change throughout the course of its service life - for example, its function can change, loads can increase or higher building standards become required and the structure must be made compliant. Historical or landmark structures may need to be reinforced in a discrete way without impacting the original design or forms.

To extend the longevity of the structure for many decades to come, structural strengthening is a safe, secure choice. Sika provides fully comprehensive, complete systems for all kinds of structural strengthening. Whether the requirement is to increase the bending, shear or seismic resistance, tested and proven Sika systems are available for use on reinforced concrete, steel, wood and masonry load-bearing structures.


Sika CarboDur® System brings over
25 years
of experience with installations all over the world.
Sikadur® adhesives come with more than
50 years
of practical experience on demanding projects.

Understanding Thrust Bearings

the carbon material used in the thrust disc has very low porosity to prevent the high pressure water from being dissipated into the carbon. Power Losses. As the thrust load increases on the bearing the power loading on the motor will increase. There is a direct linear relationship between the power consumed in the bearing and the thrust load.

NASA - Ion Propulsion: Farther, Faster, Cheaper

The trade-off for the high top speeds of ion thrusters is low thrust (or low acceleration). Current ion thrusters can provide only 0.5 newtons (or 0.1 pounds) of thrust, which is equivalent to the force you would feel by holding 10 U.S. quarters in your hand. These thrusters must be used in a vacuum to operate at the available power levels, and ...

How much power is needed to hover ? – Starlino Electronics

28/10/2015 · The Deduction. Let’s get back to the main question of this article – “how much power is needed to hover an object ?” , or in other words how much energy we need to consume per second to maintain this object “in the air”. Well, as it turns out “it all depends…”. For example we do not need to consume any energy to keep a book on a shelf or a tire suspended on a rope.

Aircraft engine operation and malfunction

The air accelerated by the fan in a turbofan engine contributes significantly to the thrust produced by the engine, particularly at low forward speeds and low altitudes. In large engines, such as the engines that power the B747, B757, B767, A300, A310, etc., as much as three-quarters of the thrust delivered by the engine is developed by the fan.
