REDUCE THE RISK OF
ORDNANCE TESTING
AEROSPACETESTINGINTERNATIONAL.COM // SEPTEMBER 109
Endevco 35C is lightweight with an ultra-miniature
footprint, making it ideal for space-restricted testing
applications. A hermetically sealed, titanium case provides
protection from humidity and other contaminants that can
degrade performance. It has been designed with a low
noise floor for a superior signal to noise ratio, fostering
accurate measurements.
The Endevco family of piezoelectric, piezoresistive, IEPE
and variable capacitance accelerometers, piezoresistive
pressure transducers, rate sensors, electronic instruments
and calibration systems ensure critical accuracy and
reliability in aerospace, automotive, defense, industrial,
medical, power generation, R&D, space, and test and
measurement applications. \\
If anything goes wrong during the
test flight of an experimental
aircraft or ordnance, the flight
safety officer (FSO) must terminate
the flight in order to protect the
public and personnel. The critical
and costly decision to terminate a
flight requires accurate real-time
location data.
Today, many flight termination
systems (FTS) employ fixed
frequency transponders, located
on the aircraft or ordnance, to
provide the tracking information.
Experience in the field has proven
that fixed frequency transponders
can add unnecessary cost,
schedule burdens and risk to test
programs. This is especially true
for transponders based on older
magnetron technology, which
often prove less reliable, more
expensive, and power hungry than
modern solid-state alternatives.
One potential problem with fixed
frequency transponders arises
when the intended frequency
range is already occupied. This
situation can require returning the
transponder was not certified for
the new frequency, additional
testing may be required to ensure
the unit is range qualified.
A far better approach is to use
user-programmable transponders
that enable the frequency to be
quickly and easily changed in the
field. Curtiss-Wright’s XPDR radar
enhancing transponders provide a
modern, low cost solid-state
design to fixed frequency
transponders that combine
ruggedness, long life, reliability,
and high performance. These
programmable units enable the
user to change transmitter and
receiver section frequencies, pulse
width, and spacing requirements
on site, reducing a process that
might take weeks to just a matter
of hours. Because these
reprogrammable transponders are
already range qualified, they
eliminate the need for
re-qualification if the frequency
needs to be changed. To further
reduce risk, Curtiss-Wright also
offers the XFT-100-1 field tester
