Effect of Aerospike on Unsteady Transonic Flow over a Blunt Body

WebThe nose cone of a missile directly affects drag and stability. The two key parameters defining a nose cone are: Fineness ratio — Length/Max-Diameter (L/D) Shape — the most common being (in approximate order of usage) secant-ogive, tangent-ogive, VK, Power-series, and conical As a rule, fineness ratio has the biggest effect.
