In a gimbal ed thrust system, the exhaust nozzle of the rocket can be swiveled from side to side. As the nozzle is moved, the direction of the thrust is changed relative to the center of gravity of the rocket. The diagram illustrates three cases. The middle rocket shows the straight line flight configuration in which the direction of thrust is along the center line of the rocket and through the center of gravity of the rocket. On the rocket at the left, the nozzle has been deflected to the left and the thrust line is now inclined to the rocket center line at an angle a called the gimbal angle. Since the thrust no longer passes through the center of gravity, a torque is generated about the center of gravity and the nose of the rocket turns to the left. If the nozzle is gimballed back along the center line, the rocket will move to the left. On the rocket at the right, the nozzle has been deflected to the right and the nose is moved to the right.

The smaller levers towards the top of the picture control reverse thrust. Notice the corresponding Aircraft engine position number engine number on each lever. Thrust levers are found in the cockpit of aircraft , and are used by the Pilot in command pilot , copilot , or autopilot to control the power output of the aircraft s engines . In multi engine aircraft, each thrust lever displays the Aircraft engine position number engine number of the engine it controls. Normally, there is one thrust lever for each engine. The thrust levers are normally found in the aircraft s center console, or on the dashboard of smaller aircraft. For aircraft equipped with thrust reverser s, the control for each thrust reverser is usually found adjacent to the corresponding engine s thrust lever. The position of each lever can be described by the current angle indicated. This is referred to as the Throttle Lever Angle or TLA . The greater the TLA, the greater the engine thrust. Throttle levers The throttle lever assembly is often designed to incorporate high pressure HP cock switches so that the pilot has instinctive control of the fuel supply to the engine. Microswitches are located in the throttle box so that the throttle levers actuate the switches to shut the valves when the levers are at their aft end of travel. Pushing the levers forward automatically operates the switches to open the fuel cocks, which remain open during the normal operating range of the levers. Two distinct actions are required to actuate the switches again. The throttle lever must be pulled back to its aft position and a mechanical latch operated, or a detent hard point overcome, to allow the lever to travel further and shut off the fuel valve.

Unreferenced date December 2009 Orphan date October 2008 Power Augmented Ram Thrust or PAR thrust for short is the term used to describe the use of exhaust gas es or displaced air from either the main engines or special assist engines in enhancing the air cushion under the wings or body of what is normally a Ground effect vehicle Wing In Ground effect or WIG craft . The system can also be used in boats to increase their top speed. The configuration can use either the exhaust gases from jet engine s or the air displaced by propeller s. This acceleration accelerated air is then either ducted fan ducted , deflected or directed in such a manner that it will pass underneath the wing or fuselage body and assist in the creation of an air cushion. The purpose of using PAR thrust is to allow the craft to take off at lower speeds than those required if the system was not used. Some craft only use PAR thrust during takeoff notable examples of this are the KM and Lun class ekranoplan Lun Ekranoplanes that situated their jet engines forward of the wing and deflected the thrust downwards under the wing. Once airborne and at a speed where sufficient lift was generated by the wings alone, the deflection could be removed. The KM required 10 turbojet s to have enough power to take off, 8 of them operating in PAR mode once in level flight, the engines could be throttled back extensively or some of them even shut off.

Unreferenced date December 2009 In a dual thrust solid fuel rocket motor , the propellant mass is composed of two different types or densities of fuel. In the case of a tandem dual thrust motor, the fuel closest to the rocket nozzle burns fast and the fuel further into the motor s body burns slower. This has the effect of giving the rocket a lot of thrust initially, accelerating it up to high speed rapidly, and then once all the fast burning propellant has burnt, the slow burning propellant begins delivering a much lower level of thrust. The first phase of acceleration is called boost and the second phase sustain . Not all dual thrust motors are in a tandem arrangement but non tandem motors function much the same they just have a different physical layout of fuel, for example they might burn from the outside to the inside, rather than from the end in. The advantage of dual thrust motors is that, if the fuel were all of the fast burning kind, the rocket would accelerate up to a higher speed initially but because air resistance increases quadratically with speed, the rocket would slow down very rapidly. This would give a higher peak speed but a lower average speed. Instead, the boost phase accelerates the rocket up to a high enough speed high enough to propel the rocket to its destination fast, but not so high as to cause too much air resistance , and then the sustain stage allows the rocket to maintain this high speed for a while until it burns out, after which time it is able to coast and slowly lose speed. Dual thrust motors are most prevalent in rockets which are atmosphere bound since they have to deal with air resistance over most of their flight. It is similar in concept to that of multi stage rockets but much simpler to design and build since there is no requirement to detach stages, have separate components, etc. DEFAULTSORT Dual Thrust Category Rocketry ... more details

A squat thrust is a calisthenics calisthenic physical exercise exercise . Also called a Burpee exercise Burpee , it typically is performed as follows From a standing position, drop to a squat position with your hands on the ground near your feet. Throw the feet back, putting yourself into a push up position. Again pull the feet forward to a squat position with hands on the floor. Stand again. Repeat many times. Performing the exercise at a fast speed maximizes its effectiveness. NOTE Although the terms burpee and squat thrust can be used interchangeably, many fitness experts maintain that there are differences between the two. However, these are only variations of the exercise itself including jumping and performing push ups.

Thrust tectonics or contractional tectonics is concerned with the structures formed, and the Tectonics tectonic processes associated with, the shortening and thickening of the Crust geology crust or lithosphere . Deformation styles In areas of thrust tectonics two main styles are recognized thin skinned deformation and thick skinned deformation . The distinction is important as attempts to structurally restore the deformation will give very different results depending on the assumed geometry. ref cite journal doi 10.1016 j.marpetgeo.2003.11.020 title Thin skinned versus thick skinned structural models for Apulian carbonate reservoirs constraints from the Val d Agri Fields, S Apennines, Italy year 2004 author Shiner, P journal Marine and Petroleum Geology volume 21 issue 7 pages 805 ref Thin skinned deformation Thin skinned deformation refers to shortening that only involves the sedimentary cover. This style is typical of many fold and thrust belt s developed in the foreland of a collisional zone. This is particularly the case where a good basal decollement exists such as Rock salt salt or a zone of high pore fluid pressure. ref http www.searchanddiscovery.com documents 2007 07038hatcher images hatcher.pdf Hatcher, R.D. 2007.

Bolt thrust or breech pressure is a term used in internal ballistics and firearms whether small arms or artillery that describes the amount of rearward force exerted by the propellant gases on the Bolt firearm bolt or Breechblock breech of a firearm action or Breech loading weapon breech when a projectile is fired. The applied force has both Euclidean vector Length magnitude and Direction geometry, geography direction , making it a Vector geometric vector quantity. Bolt thrust is an important factor in weapons design. The greater the bolt thrust, the stronger the locking mechanism has to be to withstand it. Assuming equal engineering solutions and materiel adding strength to a locking mechanism causes an increase in weight and size of locking mechanism components. br Bolt thrust is not a measure to determine the amount of recoil free recoil .
