Abstract: A scramjet engine with a novel isolator is disclosed herein. The scramjet includes an air inlet configured to receive and direct air into the engine and a combustor operable to receive air from the air inlet and combust fuel therein as is conventional. An isolator is positioned between the air inlet and the combustor. The isolator includes a primary flow path separated into a plurality of separate secondary flow channels formed therethrough. The smaller secondary flow channels prevent shockwaves from propagating upstream from the combustor to the inlet that can occur during some operating conditions of a supersonic combustion flow process.

Abstract: A clamp device (1) having first and second body portions (10, 20) adapted for connection together, and having at least one fastener (50) adapted to fasten the body portions together. The clamp device has a locking member (61, 62) adapted to lock the fastener to at least one of the body portions. Typically the locking member locks the fastener to one of the body portions to create a hard joint between the fastener and the body portion, in which the fastener is tensioned to a high tension, and a soft joint between the first and second body portions, which is subjected to a lower tensions than the hard joint.
