Individual test cylinder for rocket test rig
FORM+TEST supplied test cylinders for tests on an ARIANE 6 rocket segment at the VZLU (VÝZKUMNÝ A ZKUŠEBNÍ LETECKÝ ÚSTAV, A.S, CZECH AEROSPACE RESEARCH CENTER) in Prague.
The special feature about the test cylinders is the high-precision measuring technology for the force with several redundant measuring circuits. In interaction with the control technology available at the customer, the calibration class 0.5 could be proven to 1% of the nominal load, both in tension and in compression. Appropriate swivel bearings were provided for connecting the cylinders. After the successful calibration and commissioning, we asked Jan Heřman (responsible for measurement and control technology in the aviation team) to report on his experiences
Jan Heřman: “The equipment of FTS fitted to our test rig and was working during the tests without problems.”
FTS: What was the special feature that was specifically implemented in the chosen solution by FORM+TEST
Jan Heřman: “Precise differential pressure force measurement”
FTS: How did you find the communication with FORM+TEST and the technical advice.
Jan Heřman: “Excellent communication, really oustanding in compare to the others”

FORM+TEST does make no Rocket-Science....
….but supports to create some. FORM+TEST therefore delivered 6 high precision differential cylinders with up to 2 MN in tensile load, equipped with several measurement loops for force using highly accurate load cells and pressure transducers. This enables applying and measuring loads with a repeatability in the range of only several Newtons.
