This is a suggestion and a request for feedback regarding testing and development of the Papp engine.
It seems to me that a potential cost effective way to get the Papp piston instrumented to record how it reacts to experimental detonations of various gas mixtures is to use a Single-Axis, High-g, iMEMS Accelerometer that can be mounted on the piston stem. http://www.analog.com/en/mems-sensors/mems-inertial-sensors/adxl193/products/product.html#product-samples-nav This type of accelerometer can sustain a maximum acceleration of up to 4000G. They are also cheap with a cost of under $10. It will not break the bank to upgrade the performance of the accelerometer through chip replacement if the shock performance is too low. The output of the accelerometer chip can be fed into an oscilloscope to visualize the output data. This type of detector may be more sensitive than a gas pressure change detector for characterizing the force imparted onto the piston by the blast wave of the spark. Also, it may be possible to setup a circuit that might measure the speed of the shockwave traveling through the gas by determining the Delta- time difference from the first application of the current producing the spark discharge to the associated induced piston reaction movement as measured through the output of the accelerometer. It also may be possible to calculate the force that the piston produces from the output profile of the accelerometer. Reaction and suggestions to this idea are now solicited.
