Hilton has described a relatively inexpensive subsonic ram-jet installation which may be used as an aid to technical education. This type of equipment should serve to enable students to undertake performance studies of propulsion systems. To this end, this author would like to elaborate on one of the testing phases suggested by Hilton, that is, the tests on combustion systems with direct coupling to the air supply. It is the purpose of these remarks to present some previous observations on the combustion characteristics of a subsonic ram-jet which will serve as a useful demonstration as well as to provide areas of interest for academic investigations.

Abstract This paper presents laboratory performance testing of new technology utilizing a textured raised pattern on filled restructured PTFE (R-PTFE) sheet gasketing. The technology published in PVP2018-84039 and PVP2018-84040 and presented in Prague1,2 examined the load retention attributes of filled PTFE sheet gaskets with hexagonal/honeycomb surface texture in a miniaturized and standard raised face flange joints. This paper will show performance characteristics and comparisons to flat traditional R-PTFE gaskets. Data is presented on leak performance based on DIN-3535-4/6 and EN 13555, deflection under compressive load, bolt load retention and ASTM F36 compression and recovery. The paper gives a summary of results from a study of PTFE gasket users expressing their needs and desires for gasket performance. Examples of current field cases from chemical processors are also be presented.
