Also described are a main wing of a wind tunnel model aircraft having an adjusting and fastening system which includes at least one locking fastening device and at least two adjustable fastening devices for adjusting and fastening an aerodynamic additional body that is adjustable relative to the main wing by means of a plurality of retaining devices, as well as a wind tunnel model aircraft having such a main wing.
摘要:
Device, system, and method are described directed to seal assemblies with support to reduce seal extrusion under high to very high pressure changes due to repeated piston reciprocating movement. In some examples, concave features are incorporated on the inner and outer edges of support and backup ring elements to support and hug the preceding element and constrain extrusion, as well as utilizing multiple contact points on certain elements in order to reduce friction against the dynamic surface. The seal assemblies described herein can also incorporate bearing surfaces to reduce damage to seal ID due to off-axis floating rod, such as incorporating one or more multi-point contacts to reduce friction.
