I have known Brian Murphy since the days of RAPP and PUP. XLRotor is an excellent rotor dynamic analysis software. I have been using XLRotor since its inception and found the program to be very user friendly and easy to learn. The spreadsheet format allows varying degrees of analysis in a time efficient manner, quick and easy checks on the input data, and flexible format plots to satisfy changing customer needs and API requirements. The bearing and seal codes are tops in the industry. If you have any questions on the software or rotor dynamics in general, Brian and Daniel are tops in their field and respond in a timely manner.
