PRELIMINARY VERSION -- A WORK IN PROGRESS The following dimensions should be considered a guide only. An engine built to these dimensions should produce the required amount of thrust but other factors, such as the accuracy and quality of construction may affect performance. The formulas used to calculate these dimensions are defined and explained in my pulsejet book. Gaining an understanding of how these dimensions are calculated will certainly help in refining the design presented here so as to obtain even more power. Note that the diagram below is not drawn to scale.
