For the pull propeller it is always driven with the help of an engine being coupled with crank shaft and for the push propeller it has been always driven with the help of chain drive or by the pulley arrangement which means an propeller is connected to the wheels of the vehicle through a chain or belt drive. So, that when the wheels rotate it will rotate or spin the propeller in order to produce thrust for the forward movement. With reference to the paper “ Analysis of Down-Wind propeller Vehicle” the selected Airfoil is NACA 6412 which does very well with the performance and a wind driven vehicle travels faster than the wind along its direction. The analysis i carried out in the Java Prop software to study the behaviour of NACA 6412 airfoil selected as push propeller to fly the bike in air to have the less induced drag and also with minimum drag for the same amount of lift and wing area. Even for the Wind Turbine it has been chosen best according to the paper” Design and Blade Optimisation of Contra rotation double Rotor Wind turbine” for its optimum results for the 3 blades with 600 mm diameter in the front and rear.

These flight profiles fundamentally change the free-stream conditions in which the aircrafts operate. In the transonic speed the presences of nonlinearities adversely affects the aerodynamic performance on an Airfoil. The present work deals with the comparative analysis of variation in Angle of attack and Mach number over NACA0012 Airfoil. The Transonic Compressible flow simulation has been carried using Spalart-Allmaras and k-ω turbulence model and PRESTO solution technique has been applied to govern Euler and Navier-Stokes continuity principle. with the help of Aerodynamic Characteristic of airfoil such as Static and Dynamic pressure, Skin friction coefficient, wall shear stress, turbulence intensity in transonic regime the performance parameters of airfoil such as Angle of Attack, Lift Coefficient, Drag Coefficient has been analyzed and predicted with the help of Finite e...

The rotary joint thus allows the air to flow through itself along with providing the rotary motion of the wheel assembly. Thus the rotary joint makes it possible work out the idea. A compressor is used which gets its power supply from the battery. When the pressure falls below desired level the compressor pumps air through the rotary union to the Tyre and inflates it.

A lifting hook is usually equipped with a safety latch to prevent the disengagement of the lifting wire rope sling, chain or rope to which the load is attached. Crane hook are always subjected to failure due to accumulation of large amount of stress concentration which can eventually lead to its failure. To study the stress pattern of crane hook in its loaded condition, a solid model of crane hook is prepared with the help of Creo Parametric 2.0 (Computer Aided Three Dimensional Interactive Application) software. Pattern of stress distribution in 3D model of crane hook is obtained using ANSYS 15.0 software. In this present work, the obtained stresses by using finite element analysis and Winkler-Batch method in different cross- sections are compared & to reduce the stress formed in sections by changing its design parameters (changing the mass of material in trapezoidal section). The stress concentration factors are used in strength and durability evaluation of structure and machine element. It is observed that the stress is affected if the weight is increased.

Various research and analysis has been done for the improvement and development of Airfoil in transonic regimes by means of Computational Fluid Dynamics (CFD), Direct Numerical Simulation (DNS) in form of analytical model and various experimental approach has been carried out by researchers in the field of transonic aerodynamics in order to overcome the trouble shoot occurs in form of instability and irreversibility during transonic and subsonic flight. During transonic flow Airfoil of Air vehicles exhibits shock wave in form of instability and If these shock waves are not been analyzed this may leads to tragic failure Since airfoils are subjected to both static and dynamic loads, due to which it pose great challenge to analyze the aerodynamic characteristics of an Airfoil.
