Design of Next Generation Civil and Military Aircraft with Ultra-High Bypass Engine using Composites, Advanced Materials and Technology

AbstractIndirect combustion noise had not been attracting research in the past, but recent indication seems to prove that it could be a threat in the future if not addressed. Means of reducing this type of noise to a low decibel value was also included. Noise is due to the ingestion of distorted atmospheric turbulence, as the two set of blades rotate in different direction. Open rotor noise is higher since the rotors are fully exposed to oncoming turbulence and lack ducting or a nacelle to at...

DESIGN AND CONSTRUCTION OF ICU/REHABILITATION ADJUSTABLE BED USING LOCALLY SOURCED MATERIALS

The focus of this project was the development of an ICU/Rehabilitation adjustable bed for the hospital and home environment. The project was initiated with the desire to develop an innovative, effective and inexpensive mechanism that would require an electrical supply. The design was performed systematically using various methods, procedures, techniques and materials to aid the process. One of the method used is carpentry, which was used to make the bed framework and the adjustable floo...

Energetic and Exergetic analysis of waste heat recovery system in sulphur acid using organic Rankine cycle.

The continuous search for sustainable alternative energy to non renewable energy to mitigate environmental pollution has made waste heat recovery from industries process, material and energy streams frontier. Power plant technologies like steam and Organic Rankine cycle are been research by researchers to improve waste heat recovery efficiency and energy utilization. In this study Hexane and Toluene are the organic fluid used .Their performance inwaste heat recovery in the melting furnace...

DESIGN AND CONSTRUCTION OF A SELF FEEDING CASSAVA GRATING MACHINE

This project seek to modify the existing cassava grating machine to make it to be self-feeding in operation, to make the operation of the machine easier, safer The existing processing techniques used in the production of cassava starch and cassava dough leaves much to be desired. There are difficulties in the grating of the cassava dough, since the conventional methods available is time consuming and labour intensive. In the modified design, two side hopper, belt drives, gears and pulle...

Development of Autonomous Lawn Mower from Locally Sourced Materials

A lawnmower is a machine that uses a revolving blade or blades to cut a lawn grass. Many designs have been made, each suited to a particular purpose. Manual grass cutter has environmental issues regarding pollution's and also require the need of man power to operate and has a great maintenance to its engine. This robot is design to be environment friendly and operated by a rechargeable battery and can be describe as an intelligent robot because the micro-controller receives information from s...

Design and fabrication of a PET (Polyethylene terephthalate) crushing machine.

Due to the need for recycling Polyethylene terephthalate (PET or PETE) materials, especially bottles because of its various uses and applications, it was necessary that a locally made machine for crushing and shredding the PET materials was fabricated. The crushing process is necessary so as to aid the transportation and workability of the material. This is a paper work for the activities carried out in the design, construction and fabrication processes.

Design and Fabrication of journal Bearing Testing Rig

ABSTRACT This project work deals with the design and fabrication of a suitable journal bearing test apparatus which can help in visualizing the behavior of journal bearing and its characteristics, and in determining the bearing parameters such as load bearing capacity, maximum oil film temperature, viscosity of lubricant, oil film pressure, and coefficient of friction based on experimental analysis. The work covers the design of a test apparatus which can be utilized to check the be...

Energy Audit, Optimisation and Management of Liquified Natural Gas Plants With Renewable Energy Resources Around the Plant: A Case Study of Brass LNG Limited, Brass Island, Nigeria

An energy audit on the Brass Liquified Natural Gas plant at Brass Island former Agip facility was carried. The average offshore windspeed and wave return periods for 12months  were measured for their wind and wave energy potentials. Also,  the solar insolation for the location was collected for a 12month period. A pilot design based on techno-economic analysis was made for a wind-solar- gas turbine hybrid power system and results showed it's cheaper, environmentally friend, and more efficie...

EVALUATION OF MECHANICAL PROPERTIES OF ALUMINIUM ALLOY REINFORCED WITH RICE HUSK ASH AND GRAPHENE HYBRID METAL MATRIX COMPOSITE

ABSTRACTComposites have been developed with great success by the use of reinforcement. Monolithic materials cannot possess all the properties to be obtained hence, the need to employ the use of composite materials. Aluminum is generally utilized as a basic material particularly in the aerospace industry in view of its light weight property Be that as it may; the low quality and low melting point were continuously an issue.However due to these limitations, intense exploration on the use of met...

Design of a Food Noodles Extrusion Machine.

The fast growing and developing population of the world is so busy that instant food noodles are gaining ground for both humans and domestic animals. Incidentally, the machines involved in the production of these food noddle extruders are imported which results in the depletion of our foreign exchange reserve. Consequently, there is a growing need to design and produce these machines locally. This project has achieved the design, fabrication and testing of noddle extruder. The fabrication is ...
