Aircraft; Procedure
After a 1.1 hour pattern work flight with a student; the student had controls and was taxiing back from Runway 35 via G; A; C - Cross Runway 23 (Per ATC instructions). After the turn was made from Alpha to Charlie; we continued down Charlie back to our parking location. While we were taxiing; we noticed a Falcon with its engine cowls open sitting on the GA ramp; with two maintenance personnel 'working on the aircraft'. The Falcon was pointed with the back of the engines facing the taxiway (C) at a 90 degree perpendicular angle.  As we taxied past; our aircraft all of the sudden began a sharp turn towards the Falcon (assuming from jet blast on our tail); and I took controls from the student. The aircraft went into a nose down attitude; with only the nose wheel and the right main wheel touching the ground. Close to a prop strike. I used the flight controls to keep the aircraft from flipping/prop striking; and we continued past the aircraft to our parking location after I recovered the aircraft. The maintenance personnel on the Falcon were running the engines up on the Falcon with no regard for other aircraft taxiing past; and no notice given to ATC that they would be running up blasting the taxiway. A post-flight inspection found no damage to the aircraft or propeller; the student however did hit his head while being 'tossed' by the Falcon's jet blast. No visible injuries to the student; just shaken up a bit. To prevent a future incident like this; I would suggest that aircraft running up their engines at AZO DO NOT use the GA ramp pointed back towards the taxiway; and they find a different spot on the field where that risk is mitigated.
Flight Instructor reported that while taxiing behind a Falcon performing an engine run up; the airplane encountered jet blast resulting in a loss of aircraft control.
