Projectile Motion: Example

12.4K
The theory of projectile motion is very useful for players of several sports to improve their performance. For example, a javelin thrower needs to throw their javelin in such a way that it travels as far as possible. The javelin thrower takes a short run-up to increase the initial speed of the javelin. The range of a projectile is at its maximum at a 45° angle so javelin throwers try to angle their throw as close to 45° as possible.
When we speak of the range (R) of a projectile on...

Area of Science:

  • Ballistics and projectile motion analysis.
  • Sensor technology and data acquisition.
  • Computational modeling and algorithm development.

Background:

  • Conventional dispersion measurement methods fail for multi-barrel rapid-firing guns (MBRFGs) due to multiple projectiles intersecting detection planes.
  • Accurate measurement of projectile flight parameters is crucial for performance evaluation and system optimization.

Purpose of the Study:

  • To propose a novel method for measuring flight parameters and recognizing trajectory lines of multiple projectiles.
  • To enhance multi-projectile detection capability using an integrated seven-light-screen array sensor (seven-LSAS).

Main Methods:

  • Development of a seven-light-screen array sensor (seven-LSAS) integrating multiple light-screen modules.
  • Establishment of a mathematical model based on ballistic principles for calculating flight parameters.
  • Application of a full-moment vector space and a collinearity judgment algorithm for trajectory recognition.

Main Results:

  • Accurate recognition and calculation of flight parameters (impact coordinate, velocity, angles) for multiple projectiles.
  • Measurement error for impact coordinates not exceeding 5 mm.
  • Achieved a 50% improvement in recognition accuracy compared to existing methods.

Conclusions:

  • The proposed seven-LSAS method effectively overcomes limitations of traditional testing for MBRFGs.
  • The developed recognition algorithm ensures accurate trajectory identification and parameter calculation.
  • The method demonstrates significant advancements in multi-projectile dispersion measurement accuracy and feasibility.
