This SAE Aerospace Information Report (AIR) has been written for individuals associated with the ground level testing of large turbofan and turbojet engines, and particularly those who are interested in infrasound phenomena.

This SAE Aerospace Information Report (AIR) provides descriptions of test procedures and established practices for the application, use, and administration of the conduct of icing testing for all types of turbine engines in conventional supercooled liquid (14 CFR Part 25 Appendix C) environmental conditions in ground test facilities (sea-level and altitude) for icing certification purposes.

This document is offered to provide state-of-the-art information about design factors that must be considered in the design of new or significantly modified engine test cells used to test propeller equipped turboprop engines in either QEC or bare engine configurations. The report does not address design considerations for test cells designed to test turboprop engines with dynamometer type load absorption devices because they are essentially tested as turboshaft engines. Design considerations for those test cells are presented in AIR4989, Reference 2.1.
