Introduction To understand aircraft propulsion it is important to understand the term propulsion first. Propulsion is a means of producing force required for movement of object. The propulsion system has some source of mechanical power and some means of using this power to generate force such as wheels, propellers, legs, etc. Nobody can precisely tell the origin of mankind’s desire to fly as it is lost in the distant past. There are legends of people strapping birdlike wings and jumping of a…

Catapults made a big impact in the history of aircraft carriers with the long process to launch. Catapults changed the way the US Navy launched fighter planes off carriers. Without the catapult technology, and the ground crew on aircraft carriers, The U.S would have not been able to launch planes off carriers because planes didn't have enough runway to go full speed to take off. One of the most important things before launching an aircraft is the ground crew. The ground crew gives the pilot…

just like a normal car and in the each cylinder is a space where piston movement occurs. In an article written by Brian Rohrig he writes “The faster the pistons move up and down, the faster the crankshaft rotates. And the faster the crankshaft rotates, the faster your car goes.” The crankshaft allows the tires of the car to spin, so if the pistons are moving faster the crankshaft operates more effectively and so does the car. The piston movement is the most important part of the engine because…

Eastern Conference Central Division fourth ranking team Detroit Pistons defeated the conference leader Cleveland Cavaliers with a 96-88 victory at the Quicken Loans Arena Monday night. Pistons guards Reggie Jackson and Kentavious Caldwell-Pope led the Auburn Hills-based three-time NBA champion club to withstood the late comeback run of the Cavs to end a five-game losing skid. Jackson dropped 23 points, with 4 assists, 3 rebounds and 3 steals while Caldwell-Pope added 19 points. 4 rebounds and 2…

Engine assessment Petrol engines. A petrol engine is an internal combustion engine with spark ignition, designed to run on petrol and homogeneous hazardous and unstable fuels. The first petrol combustion engine was prototyped in 1882 in Italy by Enrico Bernard. The pre commixing was afore now done in a carburettor, but now it is done by electronically controlled fuel injection, except in diminutive engines where the cost of electronics does not give a substantial reason for the integrated…

You might think you know about cars and about their history, but infact, you don't know the half of it. However, you will by the end of this paper. The first thing you have to realize is that Merriam Webster defines an automobile as a self powered transport device, usually having four wheels; now having said that, that is only the tip of this iceberg. For example, did you know that the idea of cars go back as far as the 1400’s. In 1478, Leonardo da Vinci designed a self powered, cart-like…

variable. The system volume was set by placing the piston about halfway through the cylinder to allow room for it to move up and down with the resulting volume change. The temperature was varied from a near-boiling temperature to a near-freezing temperature. The canister was placed into the water of the varied temperatures to change the temperature for the system. Each temperature changed the volume of the system as seen by the movement of the piston. The change in height was recorded and then…

With piston engines the maximum pressure is higher and with the same fixed inner airflow, it produces more power. The most important drawback of this model is the weight, piston engines weight more than turbines and the increase of weight would be important.In the 70s and the 80s, different companies like Rolls Royce, have been unsuccessfully attempted to design an aeroengine which combines both engines, pistons engines and turbines. One solution to this issue is replace the piston engine for…

to get for the pistons.  The lowest price that I hoped to achieve was the market price of $560, but I would be willing to go lower if needed since the alternative was to get $100 but try my best to not go below $480 as that is the production cost.  I would go down on the rush fee or insurance fee in exchange of Excalibur branding.  The last hurdle would be to convince them to buy from Excalibur instead of a cheaper competitor who would take longer than wanted to get the pistons ready. By…

Diesel engine The diesel engine (also known as a compression-ignition engine) is an internal combustion engine that uses the compression to initiate ignition and burn the fuel that has been injected into the combustion chamber. This contrasts with spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline), which use a spark plug to ignite an air-fuel mixture. The diesel engines have the highest thermal efficiency in any internal…
