ADJUSTABLE TUNER THERMAL STUDIES The mechanical design includes the thermal studies to reduce the pressure drop and to ease the flow circulation. | PAGE 14 8/9-Dec-15 CDR2 - Mechanical integration - H. PRZYBILSKI / P-A. LEROY d Shape

ADJUSTABLE TUNER PROBLEMS Bellows supplier has no experience in putting a bellows in a brazing oven. The thermal treatment will reduce the life-cycle by a factor 2. It means 5.000 cycles instead of 10.000. There are 2 kinds of bellows: Donc il est nécessaire de passer par une phase de R&D. | PAGE 15 8/9-Dec-15 CDR2 - Mechanical integration - H. PRZYBILSKI / P-A.
