A cryogenic rocket engine is a rocket engine which utilizes a cryogenic fuel or oxidizer that implies fuel and oxidizer are liquefied gases stored at low temperatures. These engines were important factors for ultimate success to reach the Moon by the Saturn V rocket.

American and Soviet engineers discovered that rocket engines require high mass flow rate of fuel and oxidizer to generate a thrust in which oxygen and low molecular weight hydrocarbons used as fuel and oxidizer pair. Both are in gaseous state at room temperature and pressure. If propellants stored as pressurized gases then the size and mass of fuel tanks decrease efficiency of rocket to obtained the mass flow rate.

The combination of liquid hydrogen (LH2) fuel and liquid oxygen (LOX) oxidizer is widely used which are cheaply and easily available. It has the highest entropy released by combustion if burned.

 Conclusion:

This Cryogenic Rocket Engine Hydrogen Fuel System project concludes that the cryopumps are turbo pumps which are powered through gas turbines differentiated into a bypass flow configuration or main flow configuration.

It is known that when the inlet air is cooler, the engine has more power. Consider aspirated, supercharged gasoline engines, and turbocharged diesels whereas supercharging increases the oxygen amount in the cylinder that supports combustion of fuel. It is expected because of atmospheric pressure with cylinder filling.

Airflow makes engines power to be more in several methods. The more air is flown through an engine, the more oxygen will be present for burning fuel. More oxygen implies that more fuel is burnt which means more power.

Nitrous oxide increases the amount percentage of oxygen effectively to have a mixture of air, nitrous oxide, and fuel. It means that more fuel is mixed into the working fluid for combustion heat, to expand the working fluid, and increase pressure in the cylinder.

When the compressed nitrous oxide is stored as a liquid in its pressurized container, it depressurizes and changes from a liquid to gas state. It cools the working fluid and an incredible amount of nitrous oxide is being used and nitrous oxide injection is used at wide open throttle.

The air throttle on a gasoline engine controls the density of the intake charge to enter into the cylinder. Increased density implies that molecules get closer together in the air. It is considered that increased air density in unconfined and confined spaces. There are two things that affect air density in the atmosphere pressure and temperature. When atmospheric pressure increases on a barometer then the density also increases and temperature remains same.

Conclusion:

The conclusion is that an engine is normally aspirated or supercharged, gas, diesel, the cooler the intake air, the better. Intercoolers are necessary for every turbo car. The intake charge temperature is important in performance of turbo vehicle and intercooler prevents compressor surge and kills turbo. Intercoolers improve efficiency and power of turbocharged application.

The aim of this Construction of Test Apparatus to Identify Different Types of Wood Mechanical Project study is to recognize the wood example by inserting a nail by a hammer that is swung on the test device to insert the nail deeper into the device with a stroke. The test device made and wood specimens examined on the device. The equipment allows inserting the hammer to be managed and hence allowing constant strikes on hammer to obtain with each example.

 On noticing the depth of piercing of nails that is obtained by consistent number of blows and the resistance provided is attained by the wood practically. The hammer strikes the nail by wood structure. When the nail theoretically penetrates through, it forces the cellulose fibers that are very strong tied with lignin. Hence, these determinations of force to pierce the nail are done completely.

 The difference among softwood and hardwood includes plant reproduction. The trees reproduce seeds and seed structures are different. Hardwood trees are angiosperms and plants which form seeds with kind of covering like apple and acorn. Softwoods are gymnosperms. These plants produce seeds which fall on the ground without covering like pine trees that produce seeds in hard cones.

 Conclusion:

 The wood from various kinds of trees include various properties. For instance, Maple wood is very hard. It is simple to curve the nails to pound into the form of maple. Unlike Maple, Pine lumber is soft which can be marked with fingernails. Hence, the information of piercing of the nail can be obtained and achieved with many kinds of wood and help to recognize the wood by providing resisted forces.

Coconuts are dehusked generally by machete or a spike manually. These procedures require skilled labour which is tiring to use and steps are used to develop dehusking tools. These are successful partially and not effective to replace manual procedures. The failure of these tools is because of unsatisfactory and incomplete dehusking, breakage of the coconut shell during dehusking, spoilage of useful coir, greater effort needed than manual methods, etc.

 This Coconut dehusking Machine Mechanical Engineering Project includes the design, development, and testing of a coconut dehusker to overcome the failure of the previous implementation. The unit dehusk to about 70 coconuts per hour comparing to 40 nuts per hour with the use of spike method. It is operated by unskilled labourers.

 Coconut is the fruit of the coconut palm tree where India is a leading producer of coconuts. This fruit is large, dry drupes, ovoid in shape. There are various ways to dehusk the coconut which is done manually, mechanically and by machines as well.

 The coconut husk is peeled off by the coconut dehusking machine from coconut fruit to obtain dehusked coconut fruit by mechanical controlled dehusking devices. The important parts in the project are hydraulic pump, cylinder, coconut holder mechanism, height adjusting knob, and poker arms.

 Conclusion:

 The time and cost is very important in today’s modern world hence to get rid of this, this project has designed and fabricated the machine “Coconut dehusking machine” that reduces the cost and to saves human energy. The machines such as manual, traditional, electronic and hydraulic machines need minimum human effort and there are many advantages with these machines.
