Rotorcraft Propulsion System Airworthiness Qualification Requirements; Ground and Flight Test Surveys and Demonstrations

The surveys and demonstrations herein are normally divided into two segments; an
initial series of propulsion interface surveys and subsequent propulsion
demonstrations. In effect, propulsion surveys are considered a subset of the more
formal propulsion demonstrations leading to airworthiness qualification. The
original ADS—l addressed only propulsion interface surveys. This revision has been
expanded to include all propulsion demonstrations. This ADS has also been updated
to reflect current technology and lessons learned from recent flight test programs.

Propulsion surveys are conducted early in a flight test
program to obtain preliminary engineering performance data pertaining to
selected propulsion systems/subsystems. Surveys ara intended to determine the
necessary design changes, if any, which must be incorporated 1.1 either the
engine, airframe, or other propulsion systems, and to incorporate these
changes prior to completion of engine qualification and/or subsequent
engine/airframe or propulsion system airworthiness qualification. Surveys are
performed through portions of an aircraft's operating envelope and over a
worst case range of c.g., airspeed, altitude, maneuver load factor, and rotor
rpm. Usually, propulsion surveys are conducted prior to completion of engine
qualification by the engine manufacturer. A test Preliminary Flight Rating
(PFR) engine(s) is installed on the test (prototype) aircraft and limited
propulsion interface ground and flight testing is conducted.

Propulsion demonstrations are normally conducted near the end of the
development program to insure the tested configuration is representative of
production hardware. In addition to validating the survey test results, as
described above, propulsion demonstrations also include a functional
demonstration of the following: compartment drainage, engine water wash,
lubrication system, drivetrain accessories, anti-ice and de-ice system,
condition monitoring/diagnostics, cockpit displays, fuel system (including
auxiliary fuel system provisions), auxiliary power unit and accessories,
environmental control system, pneumatic system, hydraulic system, and armament
gas ingestion. Any of these demonstrations can be performed early in the
program along with the propulsion surveys, particularly if program risk would
be reduced by an early investigation, providing the configuration of the
components or system does not change prior to production.
