PPRuNer’s have successfully kept this AW101 thread buried for close to two and half years, and now look what you have done......and so close to Halloween too.
Knowing how long they spend on the ground, I suspect 101's are delivered with flat spots on their boots and therefore difficult to get consistently accurate data
However, assuming a weight of around 20,000lbs, the following info for the venerable S-61N might get you going in the right direction.
Main landing gear:
# tires/gear 2
Static load, each gear (lbs) 9,400
Tire size 6.50 x 10
Tire pressure, approximate (psi) 95
total/gear (sq in) 104
Contact pressure (psi) 91
Dynamic load/ gear @ 6.56 ‘/sec. (lbs) 13,667
Nose Landing Gear:
# tires/gear 1
Static load, each gear (lbs) 3,900
Tire size 6.00x6
Tire pressure, approximate (psi) 75
area, total/gear (sq in) 37.2
Contact pressure (psi) 105
Dynamic load/ gear @ 6.56 ‘/sec (lbs) 8,310
