2 History 1950s 1970s 2012 New UTAS-W&B Lock Ring Wheel and Carbon Brake August 2009 after landing at COB Speicher in Iraq, the brakes overheated on this C-130 from the Wyoming Air National Guard. Crews cool the brakes with water to prevent a fire.

3 History USAF Wheel and Brake System Improvement Program (WBSI)

4 Overview Lock Ring (Boltless) Wheel Part Number Lock ring design, service proven on F-16 and C-5 25,000 mile wheel life DURACARB Carbon Brake Part Number Optimized 3-rotor, 6-piston design 2,000 landings per overhaul

5 Features and Benefits New wheel and brake system reduces aircraft life cycle cost compared to current bolted wheel and steel brake. Feature Benefit Faster tire change time Longer wheel life More landings per overhaul Lighter weight Lower component count Refurbishable heatsink 80% reduced tire change time (52 vs. 255 min. for current wheel) Decreased maintenance time 6 times longer life (25,000 vs. 4,220 mile life for current wheel) Fewer wheel replacements; Increased operational usage 8 times longer life (2,000 vs. 250 LPO for current steel heatsink) Fewer brake replacements; Increased operational usage 17% lighter weight (270 vs. 327 lbs. for current wheel and brake) Increased payload; Reduced fuel cost 17% fewer parts (490 vs. 587 for current wheel and brake) Reduced maintenance and logistics Allows brake carbon re-use (2-For-1) Lower cost of ownership

6 Features and Benefits Carbon refurbishment: Rotors & stators two-for-one Two Fully Worn Rotors Machine Along Green Lines

7 Features and Benefits Current steel brake hard tubing no quick disconnect New Carbon Brake upgrade introduces flexible robust hydraulic lines and self sealing quick disconnects

8 Lock-Ring (Boltless) Wheel Reduces Tire change time 80% (52 vs. 255 minutes) Eliminates Tie bolts, nuts, washers Eliminates Non-destructive inspection of fasteners Reduces Wheel parts count (Just three major parts) Increases Wheel life 600% (25,000 vs. 4,200 Miles)

9 Flight Test Video Current Steel Brake Videos Courtesy of US Air Force Conducted with new brake at 155,000 lbs. aircraft weight brakes-on speed 127 kts. Hydraulic fuses activated, preventing a major fire Aircraft taxied off runway and stopped with the assistance of reverse propeller pitch Test results reported in Lockheed FTDR- C130J-US1322, 23 Jan 1998

10 Flight Test Video New Carbon Brake Video Courtesy of US Air Force C-130E Maximum energy rejected take-off (RTO) flight test 2011 DURACARB carbon brake 90% worn brake (10% life) Aircraft weight = 175,000 lbs. Brakes-on speed = 127 kts. VS. Current steel brake New brake (100% life) Aircraft weight = 155,000 lbs. Brakes-on speed = 127 kts.

20 Summary of Benefits Brake Landings 800% More 2, Life 25 Wheel Life (K-Miles) 600% Longer 10 Brake Life (Years) 800% Longer Series2 Current

21 Summary of Benefits Brake Adjusters 50% Fewer Brake Pistons 50% Fewer Wheel & Brake Parts 17% Fewer Brake Rotors 25% Fewer Wheel & Brake Wt. (Lbs) 17% Lighter Tire Change (Min) 80% Faster Maintainability Series2 Current

22 Summary of Benefits Brake RTO Energy (MFP) 25% Higher Structural Torque (KPF) 48% Higher Brake Normal Energy (MFP) 32% Higher Performance Series2 Current

23 Summary of Benefits Field Service Comments from the field USAF is reviewing the need to utilize reverse props, as well as evaluating potential stopping distance improvements. Reduces FOD potential in the engines, especially at initial brake onset at higher A/C speeds. Oil temps stay lower, engines last longer. Antiskid system is very smooth without the shuddering common with the Mk II A/S system during maximum effort landings. Pending -1 changes remove wait time restrictions currently in the -1 for maximum, full antiskid braking effort stops.

24 Summary of Benefits Operational Cost Savings Potential Average Life Cycle Payback 5 Years or Less
