ABSTRACT
Micro air-vehicle is a small flight vehicle that uses a lift-generating mechanism that is different from the mechanism used for large aircrafts. In micro air- vehicles, one of the methods for creating lift is a special flapping mechanism, which consists of translation and rotational motions of wings. This is adopted from one species of insect Encarsia Formosa. For this purpose, a 6-link mechanism is designed for three positions of wings by synthesis using kinematic inversion, and dynamic force ....etc

ABSTRACT
Drag is a mechanical force generated by a solid object moving through a fluid. For drag to be generated, the solid body must be in contact with the fluid. Drag is generated by the difference in velocity between the solid object and the fluid. Drag acts in the direction opposite to the direction of motion of the body.
Microbubbles is a drag reduction device that reduces skin friction of a solid body moving in water by injecting small bubbles into the turbulent boundary layer developing on the s ....etc

DEVELOPMENT OF AN A/C SYSTEM USING WASTE
HEAT OF AN IC ENGINE
ABSTRACT
The refrigerating units currently used in road transport vehicle are of Vapour Compression Refrigeration system (VCRS). This system utilizes power from the engine shaft as the input power to drive the compressor of the refrigeration system, hence the engine has to produce extra work to run the compressor of the refrigerating unit utilizing extra amount of fuel. This loss of power of the vehicle for refrigeration can be neglected by utilizing another r ....etc

INTRODUCTION
One is emerging from perhaps the most deliberate and least colourful engineering fields of all: gas turbine engineering. Gas turbines are internal combustion engines, like the ones that drive cars, except that they use a rotating shaft or rotor instead of pistons reciprocating in cylinders. This makes their operation smooth and steady, which lowers maintenance costs and increases reliability. Though they became practical only sixty years ago, today gas turbines are one of ....etc

DESIGN, ANALYSIS, FABRICATION AND TESTING OF MINI PROPELLER FOR MAVS




INTRODUCTION

National Aerospace Laboratories (NAL) is
having major program to develop Micro Air Vehicles
(MAVs). Thrust requirements of MAV’s are
provided using different propulsive systems, namely
high pressure micro-jets or propellers. Commercially
available propellers manufacturer does not share the
design, aerodynamic and structural details with the
end users. Design of prop ....etc

ABSTRACT
The overall goal of the work presented in this thesis is to extend the physical understanding of the external aerodynamics associated with the rotating case of Hovering Rotor using Computational Fluid Dynamics (CFD) technique.
Rotating blades encounter tip vortices coming from preceding blades, which results in Blade Vortex Interaction(BVI) responsible for producing dynamic effects. Understanding the complex flow field due to this dynamic effects produced by wakes is therefore very important for the prediction of effects such as blad ....etc
