Innovation in Brake Control
Technology Evolution
Mk1
Crane introduces first antiskid in 1947
Crane introduces first wheel
speed transducer
 Electronics to drive rate sensing
 Linear four-way pressure control valves to
modulate brake pressure
 Improve brake control efficiency & reliability on all
pavement conditions
Mk3
Crane Introduces first adaptive
control
 Based on maximum braking under all operating
conditions
 Higher response Hydraulic control valves
 Improved brake control, smoothness and efficiency
 Wet and dry runway performance improvement
Mk4
Crane introduces first
microprocessor based
digital system
 Improved control algorithms allowed efficiencies
>95% under all operating conditions
 Unigain antiskid valve improved system
performance under variable pilot pedal input
Mk5
Crane introduces complete
brake-by-wire system
 Very high performance digital brake control
 Latest technology used on B787 (electric brake)
Mk2

Program Overview
• USAF Wheel and Brake System Improvement (WBSI)
• Reliability and performance improvement program
managed by USAF Landing Gear Program Office, Hill
AFB
Major Components of System Upgrade
» Wheels and Carbon Brakes (Goodrich)
» Antiskid Brake Control (Crane)
Hydro-Aire, a Crane Aerospace brand, is the legacy supplier of all
C-130 brake control systems
Program Overview
• Antiskid Brake Control System Upgrade Schedule
– Qualified ….July 2010
– Production Contract awarded …..August 2010
– Functional Fit Check….September 2010
– Deliveries….October 2010 to October 2012
– Flight Test…. June 2011 to August 2011

Current C-130 Antiskid
Configuration
• Brake control systems on C-130A/B/E/H aircraft
– Mix of Hydro-Aire Mark I and Mark II
• Mark I/II Limitations
– Older technology
– Low braking efficiency by today’s standards
– Control limitations prevent efficient control of carbon brakes
to allow inherent life improvement characteristics
– Analog components
– Obsolete components
• The Mark IV digital system is used on the C-130J

Mark IV System Upgrade
• Mark IV Digital Brake Control
– Velocity Control / High Efficiency braking
• Proven Technology
– Military: C-130J, C-17
– Civil: 737, 747, 757, 767, 777, 717, most business
and regional jets.
• Fully Compatible with new Wheel and Carbon
Brake
– Enables maximum carbon braking performance
Mark IV Upgrade
Components
• Digital Antiskid Controller

Mark IV Upgrade
Benefits
• Improved Brake Control
• 20% efficiency gain on wet or icy runways
• 8% efficiency gain on dry runways
• Reduced Operating Costs
– Digital components, eliminates analog parts
obsolescence
– Extends brake and tire life by reducing “hard skids”
– FDU facilitates troubleshooting and maintenance
actions
