JSM ADDITIONAL EXPERIMENTAL INFORMATION
AIAA CFD High Lift Prediction Workshop
Many experimental details can be found in AIAA Papers 2010-0684 and 2008-0350 by Yokokawa et al.
The following provides some relevant highlights:
- The model is representative of a typical
100-passenger class regional jet airliner. It is denoted as JSM (JAXA high-lift configuration
Standard Model). The configuration chosen for this workshop is a landing configuration, both
with and without nacelle/pylon.
- The model was tested as a semi-span model mounted on a peniche
("spacer") of various heights. The data used for HiLiftPW-3 had peniche height 60 mm, with an additional separation of
10 mm between the peniche and the fuselage (to avoid counting the force on the peniche). The 10 mm gap was sealed with a
material that mitigated the flow in the gap.
- The wing elements were un-tripped (no transition fixing).
- The configuration was tested in the 6.5-m by 5.5-m low-speed wind tunnel in JAXA (JAXA-LWT1).
- Low Reynolds number (e.g., Re = 1.93 million based on the MAC)
- "Freestream" velocity approximately 60 m/s (M=0.172)
- Estimated* tunnel turbulence intensity was Tu = 0.16 percent
(via 2003 JAXA study)
* Tu levels are estimates based on the best available measurements from other tests
in the JAXA-LWT1. Use with caution.
