Aircraft Wake Vortex Scenarios Simulation Package for Takeoff and Departure

Abstract

Engineering Notes ENGINEERING NOTES are short manuscripts describing new developments or important results of a preliminary nature. These Notes should not exceed 2500 words (where a figure or table counts as 200 words). Following informal review by the Editors, they may be published within a few months of the date of receipt. Style requirements are the same as for regular contributions (see inside back cover).

Assessment of Wake-Vortex Encounter Probabilities for Crosswind Departure Scenarios

“…The design, operating sequence and the employed submodels of WakeScene-D are described in detail in [8] and will here be recapitulated only briefly. Via simulation control [12] the types of the heavy generator aircraft (A300-600, A310, A330-300, A340-300, B747-400 and B777-200) and medium follower aircraft (A320, ATR 42-500, B737-300, and Bombardier CRJ), the departure routes (see Fig.…”

“…Along the standard departure routes, curved flight also has to be taken into account. Therefore, wake-vortex evolution is predicted within control gates that are released along the flight path of the wake-vortex generator aircraft in predefined time increments of 5 s. The gates' orientations are perpendicular to the aircraft true heading and perpendicular to the flight-path angle (see [8]). For the identification of potential encounters wake-vortex tracks and aircraft tracks are interpolated between the gates.…”

“…The validation activities for the individual submodels and databases of WakeScene-D and an estimation of the related uncertainties are described in [8]. Here, we perform a global comparison of wake-vortex transport characteristics achieved with long-term measurements and WakeScene-D simulations.…”

“…WakeScene-D (Wake Vortex Scenarios Simulation Package for Departure) [8] is an extension of WakeScene, which was developed for approach and landing and is described in detail in [9]. WakeScene-D estimates the probability to encounter wake vortices in different traffic and crosswind scenarios using Monte Carlo simulation in a domain ranging from the runway to an altitude of 3000 ft above ground.…”

“…First, this paper briefly describes the operating sequence of WakeScene-D and the employed submodels. For a detailed description of WakeScene-D, including statements of the validation work performed for the submodels and databases we refer to [8].…”
