The basic model is well, basic, with only a pneumatic adjustment for height, standard tilt and fixed armrests.
But one deal-making feature is not available, even as an option: a height-adjustable pneumatic suspension that raised the original model 2.6 inches for additional ground clearance when off-roading or storming through snow drifts.
From the shark-like, or space-ship styling to the comfortable if minimalist interior with its single spoke steering wheel and to such deft engineering as all-round disc brakes, adjustable ride height, hydro-pneumatic suspension and clutchless gearshift, the Bertoni-designed DS was a marvel.
The validated CFD model was then used in an extensive campaign of numerical tests to quantify the relevance of different design parameters such as incoming wave height and turbine pneumatic damping to characterise the hydrodynamic performance and wave energy conversion chain of the OWC.
The purpose of this study was to evaluate the ability of a pneumatic decompression belt to restore spinal height lost following an acute bout of exercise that induced compression.
Chairs with pneumatic levers allow users to adjust chair height without having to fully stand up.
Additionally, a pneumatic system lets the driver adjust the ride height of the vehicle, lowering it, say, to unload a heavy object while the Cayenne is parked, or raising it to handle challenging off-road terrain.
a) pneumatic cylinder; b) pressure regulator; c) time counter; d) height adjustment.
I kind of hope this is some sort of sick, twisted joke but apparently a 14-year-old boy in China was recently killed when the pneumatic gas cylinder – the thing that controls the vertical height adjustment — in his chair exploded, sending fragments of the chair into his rectum.
A PC based electro-pneumatic control system was designed and implemented to individually control wave height, these heights are 3, 8, 16, 18 and 20 cm and different frequencies to generate these regular and irregular waves.
