Übersetzungskulturen der Frühen Neuzeitstructural steel yielded highest fundamental natural frequency of 11.81Hz. In case of steels fundamental natural frequency depends upon the Young’s modulus of the material. For materials having higher elasticity the value of fundamental natural frequency is higher.

The target of the task is to find out the lift coefficient and drag coefficient at different leading-edge radii of NACA 2421 aerofoil and compared the results of the Elliptical, Circular, Cone leading edge of the aerofoil with standard baseline airfoil.

Martin Reichenecker,Bernhard Schweizere current study revealed that shock patterns drastically varied nearer to the nose cone model at L/D ratio 2 and variation of drag reduction occurred due to the increase in d/D ratio and aerospike and also flow pattern over the model was clearly investigated.

Regina Toepfer,Peter Burschel,Jörg Wesche and Trapezoidal) are analyzed in this study for two cases. In case 1, base area and the length of fins are equal for all profiles and in case 2, base area and surface area of all fins are equal. In this study, effectiveness of different fin profiles is calculated and compared in two cases.
