This paper tells about the CFD analysis of 2D Canard arrangement in supersonic cruise missiles. High heat dissipation rate causes the Canards to reduce its primary work of providing rotational stability to missile. This paper discusses about the criteria of choosing notched canard model against the present model. The models were designed in GAMBIT and analysed using FLUENT. Various pressure, te...
The enhancement of performance with a decrease in sensitivity of the propellant, have been considered in energetic materials research and development centers. Therefore, efforts to remove nitroglycerin from the common formulations while maintaining the efficiency of the propulsion system has been made, Which led to a new technology so called Extruded Composite Low Sensitive Propellant (ECL). Th...
In this paper, we investigate two topics related to mitigating the effect of radar bias in ballistic missile tracking applications. We determine the absolute bias between two radars in polar coordinates when their relative bias is given in rectangular coordinates. Using this result, we then obtain the optimized steady-state filter to handle the random bias.
Current study reported a facile method to investigate the effects of stacking sequence layers of hybrid composite materials on ballistic energy absorption by running the ballistic test at the high velocity ballistic impact conditions. The velocity and absorbed energy were accordingly calculated as well. The specimens were fabricated from Kevlar, carbon, and glass woven fabrics and resin and wer...
Electronic transport in ferromagnetic ballistic conductors is predicted to exhibit ballistic anisotropic magnetoresistance-a change in the ballistic conductance with the direction of magnetization. This phenomenon originates from the effect of the spin-orbit interaction on the electronic band structure which leads to a change in the number of bands crossing the Fermi energy when the magnetizati...
Elastic-recoil mechanisms can improve organismal performance and circumvent the thermal limitations of muscle contraction, yet they require the appropriate motor control to operate. We compare muscle activity during tongue projection in salamanders with elastically powered, ballistic projection with activity of those with muscle-powered, non-ballistic projection across a range of temperatures t...
