XXXIV Congress 2018

Call for Abstracts

The XXXIV Congress of the International Scientific and Technical Organisation for Gliding (OSTIV) will be held at the site of the 35th FAI World Gliding Championships in the 18m-, 20m-, and Open Class, in Letiště Hosín, Czech Republic, from 28 July - 3 August, 2018. The Congress addresses all scientific and technical aspects of soaring flight including motorgliding, hanggliding, paragliding, ultralight sailplanes and aeromodeling.

Opportunity for presentation and discussion of papers is given in the following categories:

Scientific Sessions

  • Meteorology:
    Meteorological data acquisition and service for gliding operations,
    Weather forecasting for soaring flight
  • Climatology:
    Climates that support soaring flight
    Climate change and soaring
  • Atmospheric Physics:
    Period cycles, turbulence, boundary layer in complex terrain
    Analytical techniques of delineating thermal and mesoscale structures from routine or experimental ground or flight data, or from remote sensors
    Modeling of thermals, mesoscale or microscale structures

Technical Sessions

Technical sessions will cover all aspects of design, development and operation of sailplanes, motorgliders, ultralights and solar-or human-powered aircraft. Topics may include

  • Airworthiness, structural concepts, new materials, fatigue, crash-worthiness, manufacturing processes
  • Aerodynamics and flight mechanics
  • Trajectory optimization
  • Stability and control
  • Airframe vibration and flutter
  • Propulsion systems
  • Design integration and optimization
  • New developments in flight testing
  • Airworthiness requirements
  • Cockpit instruments, including navigation instruments (GPS etc.)
  • Autonomous soaring

Training and Safety Sessions

  • Training and Safety sessions will be held on subjects covering disciplines such as
  • Flight training, theory and analysis of techniques and results, psychology, objectives, training facilities and material
  • Human and medical factors in aircraft design and operation
  • Piloting techniques
  • Flight operation in controlled airspace
  • Safety devices

Joint Sessions

Joint Sessions cover topics of general interest in the field of gliding such as

  • Soaring history
  • General philosophy of competition classes
  • Documentation of badge and record flights
  • Common interests with other air sports like hanggliding, paragliding, microlights and ultralights
  • Human-powered flight; Solar-powered flight.

Congress Presentations

Oral presentations at the Congress will be limited to 30 minutes. There is no registration fee for the Congress. OSTIV encourages submission of full papers to the international journal Technical Soaring (ISSN 0744-8996) after the Congress.

Best Student Papers Awards

Awards of EUR 200 will be presented to the students delivering the best presentations in the Scientific and Technical Sections. To be eligible, presenters must be the first author and submit an abstract and four-page summary by the aforementioned deadlines, as well as a manuscript to Technical Soaring prior to the Congress. Students who are unable to attend the Congress may designate a representative to present the work on their behalf.

Nominations OSTIV Plaque / Klemperer Award

During the Opening Ceremony of OSTIV Congresses the OSTIV Plaque and Klemperer Award may be presented to the person who has made the most noteworthy scientific and/or technical contribution to soaring flight in recent years. All OSTIV Members can send in nominations. In making such nominations, particular attention should be given to recent contributions to soaring flight by the nominee, although earlier outstanding work also will be taken into account. Nominations should include details of the nominee’s contributions and a short biography. All nominations for the OSTIV Plaque / Klemperer Award must be received by R. Radespiel, the President of OSTIV, c/o TU Braunschweig, Institute of Fluid Mechanics, Hermann-Blenk Str. 37, D-38108 Braunschweig, Germany, by 31 January, 2018.
