Pacelab Suite, APD & SysArc: What's new in 7.0

The latest major release of our preliminary design software tools introduces many new or improved features to make your work easier, more efficient and more productive. Below you can find some of the highlights of the 7.0 release.

Released November 2018

Improved handling of mass and aerodynamic chapters

The use of mass and aerodynamic methods has been improved for flexibility, extensibility and maintainability:

  • The user can now switch between alternative analysis methods by a click of a button to make it easy to adjust the level of complexity and/or accuracy, e.g. when changing from empirical to more physics-based analysis methods.
  • The software now allows quick numerical comparison of different methodologies by switching entire method sets in the scope of trade studies.
  • The code of customized methods is separated more clearly from off-the-shelf components via interfaces, streamlining maintenance and version upgrades.

Improved definition of aircraft configuration and geometry

With new and enhanced configuration options, Pacelab APD’s range of aircraft configuration topologies and types has broadened significantly:

  • A new graphical editor simplifies and streamlines the modeling of aircraft. It only takes a few steps to sketch the configuration from an imported drawing, immediately delivering a fully-fledged 3D model ready for further exploration and analysis – without requiring any CAD skills.
  • A new fuselage model handles complex shapes just as well as those known from classical tube-and-wing aircraft. The model can encompass multiple sub-components such as main body, fairings, engine inlets or canopies and delivers accurate geometric information such as wetted areas or cross-sectional distributions for use in dedicated analysis methods.
  • A new engine type has been added to the library, allowing the modeling of turbo fan engines buried in the fuselage.
  • The empennage configuration now allows for defining fin configurations with one-, two- or no fins, as well as tail-less aircraft.

Refined flight performance calculations

  • The flight performance has been improved in capability and ease of use:
  • Take-off calculations now consider speed ranges for VROT and VLOF as well as ground effects.
  • Multi-dimensional calibration of high- and low-speed drag polars has been enhanced to also cope with sparse reference data originating from flight test or numeric simulation.
  • Wave-drag estimation better models the transonic regime for use with supersonic aircraft.

Extended systems component library

A new set of electric components has been added to the library allowing:

  • The reversion of the energy flow direction, e.g. switching from discharging batteries to charging them
  • Optional liquid cooling of components
  • Parametric changes to the system voltages to assess their impact in automated trade space investigations
