to provide industry with a reference document highlighting the necessary design considerations and configuration option for an aircraft fully enclosed test facility (Hush House).

A guide to maintenance procedures in test cells. A suggested equipment monitoring and/or inspections to reduce the probability of unanticipated failures and associated test cell down time. Guidelines for using typically available data acquisition capabilities in a test cell are provided to utilize normally available trending capability to monitor the testing equipment in addition to using these tools for the usual monitoring of the test article. For the common types of test cells (turboshaft, turboprop, turbojet, and turbofan) test facilities, lists of typical systems with their associated components are provided with suggested inspection intervals and key items to look for in the inspection. A template risk assessment form is provided to facilitate the customization of the assessment of the test cell components to help predict recommended spares.

This is a SAE Standard specification with minimum performance characteristics for Turbine Flowmeter (TFM) that pertains only to sizes from ½ to 2 inches. The utilization of TFM is for hydrocarbon liquid fuel volumetric flow measurements. This Standard specifically excludes smart electronics in accomplishing the defined performance objectives. Users of this Standard should specify other TFM characteristics required to satisfy their application and utilization in operational environment. A User should understand fit and function of the TFM and define end user specific fit and function requirements. The TFM should be calibrated by the manufacturer should be based upon end user requirements and presented as Roshko versus Strouhal at a reference temperature. The Supplier shall be prepared to show evidence to User that the device demonstrates compliance with all requirements identified in this Standard.

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.

The testprocedure per the applicable Engine Manual does require a vibration check for the low/intermediate and high speed rotorsystems.

Highlight items cell design features that can make it less difficult to physically move a test cell at a future date. A relocatable test cell is one that can be deconstructed and constructed again on a new site where as a mobile test cell is routinely moved.

This document discusses, in broad and general terms, the effects of various natural and man-made influences on the design, construction, equiping, operation and long term supportability of gas turbine engine test facilities.

This SAE Aerospace Information Report (AIR) has been written for individuals associated with ground level testing of turbofan and turbojet engines and particularly for those who might be interested in investigating the performance characteristics of a new test cell design or of proposed modifications to an existing test cell by means of a scale model test.

This SAE Aerospace Recommended Practice (ARP) is written for individuals associated with the ground-level testing of large and small gas turbine engines and particularly for those who might be interested in constructing new or adding to existing engine test cell facilities.

This SAE Aerospace Recommended Practice provides recommendations for: • the audit process in general; • a list of specific areas of attention to be audited; • maintaining the test facility in such a manner that it meets audit requirements.

The paper will concentrate on the main engineering engine related aspects of the facility and will not necessarily contain information on the construction validation activities such as HVAC, electrical, facility fire system, waste water etc.
