Major components included the orbiters, recoverable boosters, external tanks, payloads, and supporting infrastructure. Five space-worthy orbiters were built; two were destroyed in mission accidents.The Space Shuttle at launch consisted of the Orbiter Vehicle (OV), one external tank (ET), and two Solid Rocket Boosters (SRBs). It was launched vertically like a conventional rocket with thrust from the two SRBs and three main engines. During launch, the external tank provided fuel for the orbiter's main engines. The SRBs and ET were jettisoned before the orbiter reached orbit.
Updraft carburetor: This type is placed low on the engine and uses a gravity fed-fuel supply. In other words, the tank is above the carburetor and the fuel falls to it. Even this carburetor uses gravity to receive the fuel from the tank, the air-fuel mixture must be forced upward into the engine 3. Downdraft carburetor: This carburetor operates with lower air velocities and larger passages. This is because gravity assists the air-fuel mixture flow to the cylinder.
The cylinder head and unitary block weight of only 6.7 Kg with complete all the accessory weights of 60 Kg. This engine displacement was 44 cubic inches that can produce the power to 26.5 horsepower and 20 KW at 5400 RPM. They could be acceleration from 0 to 60 MPH in 34 Sec, quarter mile drag time of 23.5 Sec, curb weight of 533 Kg and wheelbase 85 inches at a high top speed of 67
The Space Shuttle was introduced after the Apollo mission was a success. But unlike the last one, the Shuttle was approved for operating in space without a specific mission and goal for the mission. The Shuttle project was politically and economically not strong. It was also sold as a partnership with the ESA to improve international and social relations as it would combine people from different countries, races and sex for the crew. The Shuttle complete or exceed NASA 's promises.
These unmanned and autonomous aircrafts would be able to conduct atmospheric measurements, surveillance mission and serve as a communications relays. - 9 - Graduation Thesis Sheet NASA was interested in using such an aircraft as an “atmospheric satellite” since it would make it easier to maintain/upgrade and to control its flight path, this for a fraction of the cost compared to a traditional satellite in space. The first aircraft used in the program was the solar cell and
Despite that, they are also used in diesel compression ignition engines operating in large, weight-insensitive applications, such as marine propulsion, railway locomotives and electricity generation. In a two-stroke engine, the heat transfer from the engine to the cooling system is less than in a four-stroke, which means that two-stroke engines are more efficient. However, crankcase-compression two-stroke engines, such as the common small gasoline-powered engines, create more exhaust emissions than four-stroke engines because their petrol lubrication mixture is also burned in the engine, due to the engine's total-loss oiling
We use 12 VDC (Volts Direct Current) in our ROV. This power is used to drive motors, GSM module, etc. In our ROV, there will be a pair of small wires one negative (-) and one positive (+), for each motor or other electronics and electrical component on our ROV. Industrial ROV’s use higher voltage up to 3000V which is supplied from the surface, but this high voltage from the surface is transformed to 48V,
1. Introduction 1.1 Problem Background For years, the Internal Combustion Engine has been around, the use of ferrous alloys as its crank is mostly common. Because of the reliance on fossil fuel, these internal combustions need to be sustainable. Although efforts of finding alternative platforms for power generation like electricity and hydrogen fuel cell, these are still far in terms mass production readiness and affordability compared to the Internal Combustion Engine. To sustain remaining fossil fuels, a more efficient design must be considered in designing the crankcase for Internal Combustion Engine.

In this work rocket nozzle designed using CATIA software. Due to high temperature from nozzle
An aero engine is therefore the component of the propulsion system for an aircraft that generates mechanical power; these aero engines are almost always light weight piston engines/reciprocating engines (a heat engine that uses one or more reciprocating pistons to convert pressure into a rotating motion) or gas turbines (has an upstream rotating compressor coupled with a downstream turbine, and a combustor in between), except for small multicopter UAV which are almost always electric
