Plastic scintillators at F3 and F7 were used to determine the TOF, while ΔE was measured by a gas ionization chamber at F7 [21]. Several sets of parallel plate avalanche counters (PPAC) at F3, F5, and F7 [22], [23] were applied to monitor the trajectory of the particles. For ...
provide objective, spatially inclusive information on the relevant parameters of interest such as runout distances, jump heights, and kinetic energies as a function of the digitised terrain. While the awareness of rock shape dependence on rockfall trajectory behaviour is well established14, only the ...
Shape-changing materials open an entirely new solution space for a wide range of disciplines: from architecture that responds to the environment and medica
In the second step, the simulation model was introduced to acquire numerical predictions for a nongeneric nose configuration. Sahu [5] studied the flow control of the finned projectile to create asymmetric pressure distribution and provide aerodynamic control changing the flow field in the aft finned...
The total electron yield and the shape parameters of the DDCS were determined and compared with the corresponding values from 2nd order OBK, CDW and CDW-EIS theories. A further aim of this work was to check whether the velocity of the projectile and that of the electrons at the maximum of...
timing and calculating device (5) adapted to calculate from the time delays between the instants of reception of the pressure wave the trajectory of the projectile, a signal transmitter (9) comprising a spark generator, is used to transmit sonic signals which are detected by the transducers (3...
The analytical method, describing the shape of the temporary pulsating gunshot cavity, has been presented in this paper. A non-viscous incompressible liquid approximates the tissues of the living organism. The simple algebraic formula, determining the trajectory of the rigid projectile penetrating into...
The computed results describe the trajectory, velocity variations and the altitude loss of the projectiles with time and location. Comparisons indicate that the round nose projectile had the best performance at long distances compared to the other samples. The flat nose projectile exhibited great ...
The design for an anti-aircraft hollow projectile, provided with ample power and precision, to minimize the flight time of a given slant distance is of vital importance. With the purpose of obtaining the optimal aerodynamic shape with the shortest possible spent time of a given slant distance, ...
