The Jupiter temperature chamber (right) creates an environment that ranges from minus 70 degrees Celsius to positive 180 degrees
Celsius. All the wires connect the component being tested to the equipment that tests its functional capabilities during the test.
life with test equipment for the sections of DO-160 tests
required by certification authorities.
"We develop a lot of products, most of them require some
level of testing, and it is more cost effective to discover
and address problems revealed by testing a prototype than
the finished design, when all of the drawings have been
reviewed and approved," Moore said. If the solution to the
problem identified by testing requires a new circuit board
or metal work, changes to the design become even more
expensive.
Offering DO-160 testing to other manufacturers was
the second reason Jupiter invested in the equipment.
Travel costs to an external testing facility are a substantial
line item when certificating a product. They include not
only the manufacturer's engineers, the test units, and the
mounting racks, cables, and test equipment needed to
evaluate their operation during their DO-160 trials, they
also can encompass the costs associated with the required
participation of a designated airworthiness representative
who oversee the tests for the certification agency.
For its testing needs alone, the test equipment repaid
Jupiter's investment in a few short years. It helped, Moore
said, that a DAR resided not far from the company's
headquarters in Kelowna, British Columbia, Canada. Since
then, Transport Canada has approved Jupiter's design
approval organization, which includes oversight of testing.
This contributes to the flexible schedules Jupiter offers its
testing customers, who come across northwestern North
America, and it imposes no penalties when customers
must reschedule testing to redesign a unit to address issues
identified by testing.
Customers have to bring the units, power supplies, cables,
signal generators, functional test equipment, mounting racks,
and engineers needed to evaluate the unit's operations,
Moore said, "because we have no idea how their box works;
we just provide the calibrated DO-160 environment in which
it was designed to work, and they run all of the functional
tests." The only constraints are that the box fits in the test
apparatus, and it must not be too heavy for the vibration
table.
