This project aimed at delivering a multi-disciplinary computer program capable of simulating the noise emission and propagation of modern airplanes powered by turboshaft engines coupled to conventional propellers or advanced propellers (propfan). This document describes existing computer programs (FLIGHT and FLIGHT-NOISE) that comply substantially with the requirements of the Call for Proposals (Call). More specifically, the proposal has the following objectives:

• To produce state-of-the-art aircraft noise, emissions & propagation software.

• To validate the software with clear benchmark test cases.

• To provide support technical beyond the duration of the project.

The main project deliverables are:

1. The Software, including an “Airframe Module”, a “Propulsion Module” and “Noise

Propagation Module”.

2. Database of turboprop engine performance (flight envelopes).

3. Validated prediction tools.

4. Software documentation, including user’s manuals (20 deliverables).

The project is expected to deliver benefits in other areas, such as:

1. Multi-disciplinary approach to aircraft noise and flight operations.

2. Flexibility in predicting sources of noise, noise perception, noise propagation.

3. Engineering advancements in the areas of advanced propeller noise.

4. Prediction of combustion emissions.

This project proposed to compensate for the imbalance between the requirements of the aviation industry and the technology currently implemented in Aircraft Flight and Noise Prediction programs. In particular, noise propagation tools are currently unavailable to the industry.
