Value of LORD Embedded Sensing Systems


Variable Reluctance Torque Sensing Enabling flight control feedback and

rotating shaft health measurement

• Two sets of 3 Variable Reluctance (VR) sensors measure ferrous

targets on a spinning shaft (gear teeth, coupling features, etc.)

• Timing between the two sets of sensors used to determine shaft motion

in 5 degrees of freedom

• Able to accurately determine shaft twist to <0.001°, twist measurement

and shaft stiffness calibration used to calculate torque

• In production as flight control component on fixed-wing aircraft (DAL-A)

Wireless Torque Sensing

Enabling real-time health

measurement for rotating shafts


Torque-Link

• Scalable collar and small

electronics design enable

retrofit across broad range of

applications (<1” to >10” shaft)

• Non-contact, eliminates slip

rings for both power and

measurement

• Lossless (LXRS) wireless

communication technology

• Battery or inductive coupling

power options

• Cost-effective option for HUMS

implementation

Drive Shaft


• LORD has extensive experience meeting DO-160 requirements in

other applications, design work for compliant Torque-Link is ongoing


Ground Based Applications Industrial Fracking Truck

• Torque-Link sealed to withstand harsh environment, mounted on

>6” shaft, oldest units in field for >1 year

• Real-time wireless measurement, processing done on node to

output torque measurement to customer

• Battery powered system, >75 hours continuous synchronous

sampling at 512 Hz sample rate (highest usage mode)


Ground Based Applications Military Ground Vehicle

• Long-term, hard to access installation on <0.5” shaft

• Inductive power solution provided to eliminate battery maintenance

• Inductive solution does not require concentric coils

• Exciter range typically ~0.25”, scalable with coil design

• Inductive solution can also transmit data through near-field

communications (NFC) in applications with high levels of interference

for traditional wireless

Aerospace Applications

UAV Tail Rotor Driveshaft

•Operating speed >7500 rpm necessitated dynamic balancing on

driveshaft

•Balancing collars at three locations

•Program has successfully flown >20 flights and is ongoing



Aerospace Applications NAVAIR FireScout MQ-8B

• NAVAIR contacted LORD for a quick turn torque monitoring solution

• Testing for AGI during rocket fire event for MQ-8B weaponization

• Previous slip ring solution failed during flight testing

• LORD engineer, tested and delivered a solution in 2 weeks



• Wireless single channel sensor

• Two-piece machined aluminum clamshell housing

• Installed on tail rotor driveshaft with full bridge gage rosette



• Data captured in real-time via a chase aircraft

• Used for 6 ground tests and multiple subsequent flight tests

• Wireless data showed expected load levels and no transients

during rocket fire
