Title: Exhaust system with three-way catalyst immediately following exhaust manifold and NOx adsorption catalyst connected selectively downstream via static gas-insulated auxiliary line, solves cold starting problems
Inventor: ODENDALL BODO
IPC: F01N3/08
Filed: 1998-11-24
Abstract: A three-way catalyst (16) connects to the exhaust manifold (14) as closely as possible to the engine. An NOx adsorber (24) downstream of the catalyst is separated from it by at least 1.5 m, preferably 2 m or more. The separate internal line (36) has markedly smaller cross section, and is largely insulated by the surrounding gas inside the exhaust pipe (20) between three-way catalyst and NOx adsorber. Preferred Features: The separate line (36) runs inside the central length of exhaust pipe (20) from the front pipe section (18), right up to the NOx adsorber. An exhaust block valve (38) is located near the NOx adsorber. The separate line also extends inside the front pipe (18) to the three-way catalyst. Downstream of the three-way catalyst, a cooler-silencer section (22) is included. Its enlarged peripheral surface area, promotes heat transfer (cooling exhaust gases only when they are hot and flowing in its outer region). The separate line passes through it. The exhaust pipe and separate line comprise two double-walled C-shaped half-pipes which are connected together gas-tight, by longitudinal welded, or brazed connections. In alternative construction, continuous sheet metal is employed. An oval section, with ribs or grooves to increase area, may be used to enhance cooling at the outer periphery.

Title: Helicopter airframe with tail boom and rotor shapes boom asymmetric to main boom and rotor stream impact aided by extensible sheets or boom skin-spiralling coils.
Inventor: BUETER ANDREAS
IPC: B64C23/00
Filed: 1999-06-08
Abstract: In relation to the stream from the rotor (7) the tail boom (8) is shaped so as to separate the stream from at least one side of the boom without forming an eddy flow and this continuously along most of the boom length. Thus the boom (8) is assymmetric in the critical regions in a plane spanned by the main direction and also the direction of rotor stream impact. The rotor drive shaft (6) is run along the boom (8). Interference sheets (19) projecting from the boom (8) in the specified critical regions can be extended and/or twisted and/or swiveled relative the boom line. In a variant, the outer skin of the boom is fitted out with coils in spirals round the boom to extend from the subframe and at variable coil pitch. The coils can possibly be obtained by deforming the outer skin of the boom and the skin itself can be locally extended by pressure pads.
