Tesla Roadster (second Generation)
The Tesla Roadster is an all-electric battery-powered four-seater all-wheel-drive sports car concept in development by Tesla, Inc. Tesla has said that it will be capable of in 1.9 seconds, which would be quicker than any street-legal production car as of the announcement in 2017. The Roadster is the successor to Tesla's first production car, the 2008 Roadster. Tesla CEO Elon Musk has said that Roadster should ship in 2023. Musk said in a tweet that higher-performance trim levels will be available beyond the base specifications, including a SpaceX package that would "include ~10 small rocket cold air thrusters arranged seamlessly around the car" which would supposedly allow for dramatic improvements in "acceleration, top speed, braking & cornering" such as a claimed 1.1 second 0–60 mph (0–97 km/h) time. Overview History In 2011, at the end of the production run of the original Tesla Roadster, Elon Musk suggested that a new version of the Roadster, without the Lotus c ...

Tesla Roadster (first Generation)
The Tesla Roadster is a battery electric vehicle (BEV) sports car, based on the Lotus Elise chassis, that was produced by the electric car firm Tesla Motors (now Tesla, Inc.) in California from 2008 to 2012. The Roadster was the first highway legal serial production all-electric car to use lithium-ion battery cells and the first production all-electric car to travel more than per charge. It is also the first production car to be launched into deep space, carried by a Falcon Heavy rocket in a test flight on February 6, 2018. Tesla sold about 2,450 Roadsters in over 30 countries, ''More than 2,350 units sold through June 2012''. ''Sales during the 3Q 2012: 68 Roadsters and 253 Model S.'' and most of the last Roadsters were sold in Europe and Asia during the fourth quarter of 2012. Tesla produced right-hand-drive Roadsters from early 2010. The Roadster qualified for government incentives in several nations. According to the U.S. EPA, the Roadster can travel on a single charg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Propelling Nozzle
A propelling nozzle is a nozzle that converts the internal energy of a working gas into propulsive force; it is the nozzle, which forms a jet, that separates a gas turbine, or gas generator, from a jet engine. Propelling nozzles accelerate the available gas to subsonic, transonic, or supersonic velocities depending on the power setting of the engine, their internal shape and the pressures at entry to, and exit from, the nozzle. The internal shape may be convergent or convergent-divergent (C-D). C-D nozzles can accelerate the jet to supersonic velocities within the divergent section, whereas a convergent nozzle cannot accelerate the jet beyond sonic speed. Propelling nozzles may have a fixed geometry, or they may have variable geometry to give different exit areas to control the operation of the engine when equipped with an afterburner or a reheat system. When afterburning engines are equipped with a C-D nozzle the throat area is variable. Nozzles for supersonic flight speeds, at ...

Compressed Air
Compressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air is an important medium for transfer of energy in industrial processes, and is used for power tools such as air hammers, drills, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles. Brakes applied by compressed air made large railway trains safer and more efficient to operate. Compressed air brakes are also found on large highway vehicles. Compressed air is used as a breathing gas by underwater divers. It may be carried by the diver in a high pressure diving cylinder, or supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing apparatus used by firefighters, mine rescue workers and industrial workers in hazardous atmospheres. In Europe, 10 percent of all industrial electricity consumption is to produce compressed air—amountin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold Gas Thruster
A cold gas thruster (or a cold gas propulsion system) is a type of rocket engine which uses the expansion of a (typically inert) pressurized gas to generate thrust. As opposed to traditional rocket engines, a cold gas thruster does not house any combustion and therefore has lower thrust and efficiency compared to conventional monopropellant and bipropellant rocket engines. Cold gas thrusters have been referred to as the "simplest manifestation of a rocket engine" because their design consists only of a fuel tank, a regulating valve, a propelling nozzle, and the little required plumbing. They are the cheapest, simplest, and most reliable propulsion systems available for orbital maintenance, maneuvering and attitude control. Cold gas thrusters are predominantly used to provide stabilization for smaller space missions which require contaminant-free operation. Specifically, CubeSat propulsion system development has been predominantly focused on cold gas systems because CubeSats have ...

Acceleration
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by the orientation of the ''net'' force acting on that object. The magnitude of an object's acceleration, as described by Newton's Second Law, is the combined effect of two causes: * the net balance of all external forces acting onto that object — magnitude is directly proportional to this net resulting force; * that object's mass, depending on the materials out of which it is made — magnitude is inversely proportional to the object's mass. The SI unit for acceleration is metre per second squared (, \mathrm). For example, when a vehicle starts from a standstill (zero velocity, in an inertial frame of reference) and travels in a straight line at increasing speeds, it is accelerating in the direction of travel. If the vehicle turns, an acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
