SIBRON: the first emergency parachute with pneumatic
ejection
the
energy is provided by a gas cylinder of the fire-fighting type, loaded with
compressed air at 160 bar checkable through a fixed pressure-gauge. Pressure
variations up to 15 bar caused by thermal changes of the environment, prove the
presence of air, its pressure and the proper functioning of the gauge the
driving handle is an ergonomic handle to be gripped and pulled with one or both
hands with the required strength and for the full stroke. The strain actually
required corresponds to about 8 kg and the stroke is approximately 10 cm
the
device is made in stainless steel, which guarantees high and long resistance to
atmospherical and environmental agents and to abrasions the
parachute is made in controlled porosity fabric and with direct opening pod;
its spreading and opening time is very short (about 1-2 seconds). Resulting
stress on the craft might reach 5 g deceleration. The solidity of the structure
where it is fastened to the craft has to be checked with great care. Maximum
opening speed should not exceed 130Km/h. The
swing effect is moderate the
constraint rope out of the parachute is linked with a plastic coated very
high resistance steel cable. Maximum length of such connection (free cable +
constraint rope) must be such as to prevent, under any circumstance, the
contact of wing tips or other craft components with the parachute strings. The
constraint rope is about 3 metres long the
above-mentioned steel cable is to be fastened to the craft by means of a constraint clamp in syntetic
fibres (with a tensile strength of 7000 Kg for lenghtwise configuration) in
order to extend the bearing surface and not to weaken the hook-up point spring
catches Maillon Rapide in treated steel with double thread closure are used;
their tensile strength reaching 5500 kg at least.
