Looye 2 German Aerospace Center (DLR) 1 Institute for Aerodynamics and Flow Technlogogy; 2 Institute of Robotics and Mechatronics
2 Outline Motivation Environmental Analysis Process Process application Flight Test & Validation Conclusions and Outlook Folie 2
3 Motivation Status Quo: Increasing air traffic & public annoyance for aircraft noise Possibilities for aircraft noise reduction: Noise source modification Noise protection measures Noise restrictions (ban, curfew, quota) Operational procedures 2009 by Spiegel.de Here: Focus on approach procedure noise reduction Procedural noise reduction measures: 1. Altitude & configuration variation (e.g.: steep approach, late gear ext.) 2. Noise dislocation (routing) Combination leads to radical 3D solutions Promises significant & large-area ground noise reduction Folie 3
4 Environmental analysis process Involves various disciplines highly interdependent Inevitable for environmental analysis: simultaneous consideration of 1) and 2) balanced approach fully automated process Aircraft ground noise & emission analysis: 1. Aircraft / engine design 2. Operational procedure DLR: specialized institutes/departments with individual tools Harmonize in/output formats: Common Parametric Aircraft Configuration Standard (CPACS) XML format File wrappers Interconnect tools: PHX ModelCenter DLR wide accessible client/server architecture Tools stay at the expert DLR internal project Folie 4
5 Environmental analysis process Process input data Aircraft / engine design Flight aerodynamics If required: Noise shielding factors CPACS Noise/Emission Prediction Flight Mechanics Environmental analysis of aircraft flight trajectories Folie 5
6 Environmental analysis process Implemented tools Mission Simulation (MisSim) Input: Aircraft & engine design, engine performance, aerodynamics Object-oriented language Modelica Single aircraft model various types of runtime code here: very same aircraft model implementation as for autopilot Inverse simulation compared to autopilot: Inputs: trajectory (waypoints), velocity, acceleration, configuration Outputs: control surface deflections, thrust requirement, attitude Definition of flight trajectories: Segmentation & waypoints Parametric definition Output: Trajectory of the aircraft Process design variables Folie 6
7 Environmental analysis process Implemented tools Parametric Aircraft Noise Analysis Module (PANAM) Input: Aircraft / engine design, engine performance map, flight path, noise shielding factors (if required) Noise prediction for conventional aircraft (3D trajectories) Source models for major noise components Semi-empirical: low CPU demand & realistic physics Parametric: noise emission re config. & operating condition changes Output: Ground noise impact R. Kuchar, DLR-RM Process design objective Folie 7

9 Process application Radical operational solution: Helical Noise Abatement Procedure (HeNAP)* High initial approach altitude Spiraling final descent Predicted noise dislocation effects: 1. Noise impact concentration in area around the spiral Multiple flyover events per approaching aircraft Descent area: ideally low-populated region e.g. industrial zone 2. Significant (!) reduction along entire preceding flight path Increase in flight time and fuel consumption (!)
