Workshop Programmatics Results due end of October received one entry so far Details for both experiments available at AePW3 website https://nescacademy.nasa.gov/workshops/AePW3/public/wg/highspeed Monthly telecon slides posted as well Post-processing scripts also provided for to aid comparisons and ensure consistency of results Scheduled weekend before SciTech (Jan 21-22) SciTech is Jan 23-27 at National Harbor, MD Virtual access is now an option, requires workshop registration Must register for workshop and additional cost Cost is $300 (early registration) or $400 for AIAA members and $500 for AIAA non-members Can attend workshop without registering for conference, i.e. register for workshop only and not the conference Plan is to present all 4 working groups in serial Allow participants to see results from other WGs High Speed WG is tentatively scheduled for Sunday (01/22) Presentations Current plan is 10-15 minutes for each participant (may vary depending on number of participants) Organizing committee will provide overview of cases for each WG so individual participants can just focus on presenting their results
Progress Updates HyMAX Krishna waiting on approval to send freestream fluctuating pressure Material: 6061-T6 aluminum, https://www.matweb.com/search/datasheet.aspx?matguid=b8d5 36e0b9b54bd7b69e4124d8f1d20a&ckck=1 RC-19 Specified cavity pressure defined as absolute pressure Kirk to provide mean amplitude and PSD data (approved) Kirk to provide drawings that hold the thin panel/frame test article Encountered any issues to share with WG?
HyMAX Data Format FFT or time histories Trailing edge deflection time history Flow field data: Schlieren for shock/expansion location Andrew and Krishna to finalize format Goal is to have format defined by 11/28
RC-19 Results Duke University ???parameter is the ratio of the in-plane panel stiffness to the support stiffness To exhibit periodic response, ???is on the order 1 Cavity pressure effects Increases the static pressure / stiffness effects Acoustic resonance effects of finite cavity are not important to panel response NASA LaRC Need to adequately resolve shock to get panel pressure distribution correct
HyMAX Results NASA LaRC Need to adequately resolve expansion behind wedge shock to get peak panel pressure Resolving flow field structures is need to get correct panel response
