Lightning direct effects
Our test labs offer simulated lightning direct attachment tests to 200kA peak
current. Our testing meets all test requirements of airworthiness authorities,
including those contained in FAA AC 20-155, EUROCAE ED-84/SAE ARP 5412B and EUROCAE ED-105/SAE
Our fire resistance and fire-proof testing consists of static pressure,
airflow, vibration and static load test conditions including kerosene and
propane fire burners. Collins test labs meet all test requirements contained in
FAA AC 20-135, EASA Part 25.1191, Part 25.1193, ISO 2685.
We provide thermo-vibro-acoustic testing for structures in high SPL acoustic
environments. Collins test labs use a multi-channel spectrum analyzer for data
acquisition and online analysis. We have a progressive wave tube with a 29 in. x
39 in. test section that is powered by an air modulator rated for 30,000
acoustic watts. With our innovative equipment, we test with an Overall Sound
Pressure Level (OASPL) of 168 dB and test temperatures up to 1800° F.
Our structural tests include multi-axis loading of full-scale nacelle
hardware structures. We use hydraulic control systems with capacity for
controlling 16 actuator/load channels per controller. Our equipment includes
hydraulic test stands with hydraulic actuators rated to 100K lbs of force. We
are capable of conducting data acquisition for strain gages/loads with more than
a 960-channel capacity.
We provide mechanical properties testing utilizing Universal Test
Machines with single-axis tension and compression loading. We use six
independent load frames rated 5K-50K lbs of force. Our static and fatigue
testing with environmental chambers enables test temperatures to range from -65°
F to 2000° F. Collins testing standards include ASTM E4, E8, B557, 58, E1012,
C297, C356 and AMS-STD-401.
Our vibration load testing uses electro-dynamic shaker systems with slip
tables rated to 20K lbs of force. We reach test temperatures up to 1200° F. Collins
vibration testing standards include RTCA DO-160 Section 7 and 8 test
Collins provides sensor installations for ground and flight test hardware. We
install standard aerospace instrumentation such as strain gages, thermocouples,
accelerometers, microphones and pressure transducers. We offer customers expert
fabrication of instrumentation assemblies and mounting provisions.
Acoustic impedance and flow resistance
Collins offers acoustic resistance and reactance testing up to 6.2kHz,
measured by a 3 cm acoustic impedance tube in accordance with ASTM E1050-90. Our
test labs use steady state flow resistance measurements up to 200cm/sec flow
rates with a DC raylometer system.
Collins test labs conduct microscopic and metallurgical analysis of test
articles to 20,000x magnification. We use a scanning electron microscope (SEM)
with energy-dispersive x-Ray spectroscopy (EDS) for chemical microanalysis.
Airflow test stand
Our test labs consist of a compressed airflow stand with flow rates to 12 lbs/sec
for airflow testing with a hot flow of 2 lbs/sec at 1000° F. Collins test labs
use compressed air supply capacity of 100 psig and 6,000 scf storage.
Chemistry, process development
Our chemistry and process development consists of the valuation of metals,
paints, primers and composites. We provide corrosion studies and humidity
exposure testing using humidity and salt spray chambers. Our test labs use ovens
with and without vacuum/pressure for temperature exposure testing up to 2000° F.
Optical measurement and inspection
Collins offers professional digital image correlation that allows for
full-field measurement of strain, shear, contour, deformation and vibration. We
use Shadow Moire Fringe video and image recording for qualitative and
quantitative analysis of surface buckling. Our testing includes a 3D scanning
capability to inspect for deviations against the CAD model.
Machine shop and fabrication
Collins has a fully-equipped machine shop with capability for high-precision
parts. Our shop consists of a CNC milling center, CNC lathes, surface grinders,
conventional mills and lathes, drill presses, band saws and chop saws. We use
masterCam and Catia Software.
Our comprehensive fabrication lab has a wide range of capabilities, from
detailing precision instrumented flight test hardware to large scale rig builds.
It is equipped with a water jet, plasma cutter, CNC brake press, paint booth,
sand blaster, MIG, TIG & Arc welding equipment.
