- Improved crew and passenger safety
- Increased airport capacity via reduced air traffic separation
- Quicker recovery from airport disruption/ delays
- Greater environmental hazard awareness
Targeted benefits
- Demonstrate an instrument which can:
- Detect WV and WS in a timely manner
- Anticipate and mitigate effect of WV and WS on
the aircraft and occupants - Investigate, through simulation, mitigation via flight controls
- Develop, demonstrate and validate innovative technologies:
- UV LIDAR based
- Provide potential air traffic system wide benefits
GreenWake objectives
GreenWake Simulator
Movies of GW Simulator with new scanning pattern:
Purpose
- Evaluate the Lidar performance in realistic flight conditions/li>
- Built on existing full scale flight simulation core
- The results can be used to
- refine the instrument design
- evaluate the usability of the data for the purposes of forward flight control
Principle of operation
- “Fly” in 3D space and simulate instrument response as turbulence is encountered
- Turbulence and atmosphere considered static for the time of encounter (2 ... 3s)
- Beam scanning considered dynamic – change of LOS taken into account
- A320 used as a platform
- Vary encounter scenario and instrument parameters and evaluate the output of the instrument
- Modelling and simulation of wake vortex and
wind shear detection by imaging LIDAR system - Development of an imaging Doppler LIDAR
and fast scanning system - Development of detector and data processings
- Two detector technologies being assessed
- Integration and demonstration of the performance of the system
- Creation of 3-d visualisation of the air movement (hazard map)
