This new tool has been designed to help builders to know more about their Lego Pneumatic Engines. LPEtool manages all the important data : type of cylinder, number, switch, modified or not, dimensions… The tool calculates the maximun power (at maximun speed and pressure) and the average torque which varies with the rotation of the crankshaft.
For instance, this classic LPE with 1 cylinder provides 1.3W of power whereas the Nicjasno’s 8 cylinder big block provides 100W, that is surprising but with 1500rpm and 6 bars of pressure, it is quite normal. If you have comment, question of suggestion, feel free to comment in this post.
