Abstract: The invention concerns an exhaust silencer arrangement with a transverse exhaust silencer in a four-chamber type of construction, in particular for very small passenger-transporting motor vehicles, with a 3-cylinder rear-mounted engine and an exhaust gas turbocharger. The silencer comprises a housing which is composed of two half shells and accommodates a catalyst module in an integrated manner. The catalyst module, which does not have its own housing, forms a silencer system partition which divides the silencer into a 3-pot main chamber and an additional chamber which is in particular a resonator chamber and communicates with the main chamber via connection ducts formed in the half-shell housing.

Abstract: A process for preventing overturning during the landing of an aircraft or spacecraft using an air bag type landing impact-damping system, which is inflated with gas before the landing and from which gas is discharged via discharge valves during the landing. The process includes using as the air bag type landing impact-damping system a system that is divided into a plurality of chambers that can be inflated with gas and from which gas is released independently from one another, and that a pressure difference is generated during landing in the individual chambers of the air bag type landing impact-damping system.
