Schematics of contact force profile during a take-off process
Grahic Jump Location
A sub-ambient pressure air bearing surface padded with 3 landing pads. Pad 1 (up leading pad), pad 2 (down leading pad), and pad 3 (rear pad).
Grahic Jump Location
Contact force profiles of the three pads during a take-off process. The pad height=20 nm. The rear pad location=1.85 mm (from LE), σ=8 nm.
Grahic Jump Location
Effects of the pad height on the contact force profiles of pads 2 and 3 during a contact take-off process. The pads have a uniform height.
Grahic Jump Location
Effects of the pad height on the wear characteristics of the three pads during a contact take-off process. The pads have a uniform height.
Grahic Jump Location
Effects of the relative pad height on the contact force profiles of pads 2 and 3 during a contact take-off process. The rear pad height is fixed at 20 nm.
Grahic Jump Location
Effects of the rear pad location (measured from LE) on the contact force profiles for the pads 2 and 3 during a contact take-off process
