New season of the site is open!

Little aricle Analysis of the Table of accelerators added. The analysis of the data on multistage coilguns collected in the Table of Accelerators by January 1, 2022 was carried out. The high informativeness of the parameter G in terms of characterizing the quality of accelerators was confirmed.

Merry Christmas and Happy New Year!

New coilgun ЩУМ-105 from Megavolt added to the Table of accelerators. So, it contains data about 15 gauss guns at the moment. By New Year I will try to make some comparative overview on them.

Based on the yesterday's publication, I have proposed a new parameter for evaluating multistage electromagnetic accelerators - so-called G-factor - and a special separate table has been set up, where all the coilguns will be entered, for which there is a sufficient set of information to calculate the value of G. I ask all Gauss-bu ... Read more »

Assessment of the maximum velocity and efficiency of a multistage reluctance accelerator added to the theoretical section, finishing series of publications dedicated to determination of the basic parameters of coilguns from analytical equations for the field and forces in electromagnets.

The formulas established for the first time which describe an achievable velocity of a projectile and acceleration efficiecy for a launcher with known length and energy c ... Read more »

New E-Shotgun site added to Links page, presenting some interesting high fire-rate multistage accelerators shooting disk-shaped projectiles.

Analytical investigation of the optimal and limiting characteristics of coilgun added to the Coilgun calculations section.

With the help of analytical estimates for fields and forces derived on this page, the relations for coilguns are obtained, in particular: ... Read more »

Links page refreshed. Two sites added - Russian Megavolt's and American ArcFlash Labs. Both contain powerful and high-velocity portable accelerators.

An article describing Using 555 timer as a driver in a coilgun added to the Experiments section.

The final article concerning characterisctics of a projectile published in the coilgun's winding properties section. As results of the survey:

- a simple equation derived for the accelerating force between a ferromagnet and a coil;

- spatial distributions investigated for the magnetic field generated in a winding;
