The principal objectives of the subcommittee are:
- Identify and actively pursue cooperative technology programs, which provide a cost-effective technology base and avoid duplication of effort.
- Identify ad hoc panels in specialized technical areas and sponsor workshops to promote the exchange of technical information for the purpose of solving plume problems.
- Standardize, update, and maintain computer programs for common use by government and industry in order to describe plumes and their interaction effects in a cost effective manner.
- Define nomenclature, measurement techniques, and analytical methods in order to promote the adoption of standard practices.
- Disseminate information to the user community by means of standard plume computer codes, handbooks, special publications, workshop proceedings, program reviews, and technical meetings.
The technologies of concern to this subcommittee involve phenomena associated with exhaust plumes from rockets, ramjets, space, and gun propulsion systems as well as wakes and hypersonic flows. These phenomena can be divided into three technical areas: plume/wake/hypersonic flowfields, plume/wake/hypersonic signatures (to include electro-optical[EO], infrared [IR], and radio frequency [RF] radiation), and a broad area incorporating other plume/wake/hypersonic effects.
In addition, the EPSS Signatures panel (formerly the Spectral and In-band Radiometric Imaging of Targets and Scenes (SPIRITS) Users Group) promotes technical interchange among members of the Electro-Optical/Infrared (EO/IR) aircraft signature community from both government and industry.
