Airframe Systems Essay examples

A feed pump delivers the fuel through a filter unit to the high pressure piston pumps. The pump compresses the fuel to a pressure of 1000bar. It is then delivered into the high pressure fuel rail; this fuel pressure is independent of engine speed and injected fuel quantity. The ECU controls injectors to inject fuel into the combustion chamber by actuating solenoid valve. The system pressure, the duration of injection and the size and shape of the injection nozzle determine the fuel quantity injected. Pressure in the

At first glance, someone who doesn’t know much about either of the two engines might ask, “What’s the difference?” To the untrained eye they might look exactly alike, but don’t judge the engine by its exterior look.

Although cheaper to manufacture, piston type airplane engines require more maintenance than that of their jet engine counterparts. In fact, a jet engine can go for “3,000 hours while an overhaul for a piston aircraft is generally 2,000 hours”, Piston Engine (2011). This source goes on to compare the average top speed of a piston engine driven aircraft which is usually around 200 KIAS. This is relatively slow when compared to the average jet engine that can reach 300 KIAS.

The power system consists of a four-stroke engine, a carburettor to transform incoming fuel into steam, a obstruct to control the air-fuel ratio, transmission, and drum brakes. A cylindrical piston, made of aluminium alloy as most people

Ever since I was little I was amazed at the ability for a machine to fly. I have always wanted to explore ideas of flight and be able to actually fly. I think I may have found my childhood fantasy in the world of aeronautical engineering. The object of my paper is to give me more insight on my future career as an aeronautical engineer. This paper was also to give me ideas of the physics of flight and be to apply those physics of flight to compete in a high school competition.

The gas system is the location of the gas port on the barrel. AR uppers feature different gas systems. The main systems include carbine, rifle and mid-length.

An anesthetist would choose this type of breathing system if the patient weighed greater than 7 kgs. This system allows for the rebreathing of exhaled gases, which smaller patients may have difficulty inhaling. The components of this system are fresh gas inlet, pop-off valve, absorber circuit, manometer, 7-piece, rebreathing bag, hoses, unidirectional valves, and a scavenger system.

The flexible tubing connected to the humidifer delivers air to the patient through the mask. Make sure it has room to move freely when you turn on your side or move your head from side to side.

Air circulation is the mechanical system in a building that brings in "fresh" exterior air and removes the "contaminated" interior air. In a place of work, air circulation is used to regulate exposure to airborne impurities. It is ordinarily used to eradicate toxins for instance fumes, dusts, and vapors, in order to arrange for a healthy and safe operational atmosphere. Ventilation can be proficient by natural means (e.g., opening a window) or mechanical means (e.g., fans or blowers). Industrial systems are designed to move a specific amount of air at a specific speed (velocity), which results in the removal (or "exhaust") of objectionable noxious waste. While all ventilation systems shadow the same rudimentary norms, each system is considered precisely to equal to the type of work and the rate of contaminant release at that workplace. There are four purposes of ventilation: (a) Deliver a continuous supply of fresh outside air, (b) Maintain temperature and humidity at comfortable levels, (c) Condense potential fire or explosion hazards, and (d) Eradicate or dilute airborne contaminants.

A problem air forces were faced with was how to secretly fly over enemy airspace. However, flying above 15,000 feet without air for sustained periods of time leads to unconsciousness in humans. Originally, this problem was solved with face masks that provided oxygen to pilots, allowing them to fly up to 25,000 feet. Following the face mask, a pressurized full body suit, much like a modern day cosmonaut suit, was introduced, which extended an airplane’s reach to up to 40,000 feet. However, no pilot or passenger really wanted to be required to fully suit up every time they boarded an airplane, no matter how high they went. Therefore, the problem to be answered was how to maintain a pressurized environment with sufficient oxygen, while still allowing the crew to “work in their

The internal combustion engine is vital to the modern automobile. An internal combustion engine uses an explosive combustion of fuel to push a piston within a cylinder. The piston moves to turn a crankshaft that is connected to the car's wheels through a drive shaft. Without an engine a car could not move. The internal combustion engine has a long history of how it was improved and redesigned, without which the car would wouldn’t be able to function.

To understand how it works one must recall how a person draws juice from its container. The pressure drops in the straw as air flows in a particular speed toward the person. It causes the juice to flow towards the mouth of the person. The same thing happens inside the fuel jet. The fuel will enter the venturi, as it does it expand to make a fine spray. It expands due to the change in the cross-sectional area it transverse. What happens here is akin to what happens with a spray gun or a flexible hose. The liquid passes through a narrow pathway with a low fluid pressure and high fluid velocity. As it comes out the opening the fluid the pathway broadens; thus, its pressure rises and its velocity drops. The force it exerts on the side of the pathway causes it to expand once it's out the nozzle creating a fine spray. The fuel jet creates the same spray at the side of the venturi. This fine spray mixes with the air flowing into the venturi. As the mixture flows past the venturi the pressure rises and the fuel and air get better mixed in a wider cross-section of the tube. The stoichiometric mixture would flow past the throttle valve and then enter the intake manifold of the

That covers the basic function of an engine fron intake to exhaust. Next we will explore the relationship of Horsepower vs Torque.

This total process takes less than half a second to complete, and enables vehicles to get to their destination. Reading this paper does not qualify the reader as a mechanic, but should give the person reading a better appreciation for the vehicle. It is always good to know the basics of a car so if the car ends up in need of repair, the owner can have some information and basic diagnosis. With the knowledge gained from this paper, a basic understanding should be gained on the process of an Internal Combustion

These systems have a fuel injector for each cylinder, usually located so that they spray right at the intake valve. These systems provide more accurate fuel metering and quicker response.
