i-Spaceは双曲線3号の主要構造部で静的荷重試験を完了しました。一方、統合機体や主要エンジンの燃焼試験の進展が乏しく、開発ペースの遅れも指摘されています。

i-Space recently completed ultimate load static structural testing on both the first-stage methane tank and the second-stage common bulkhead tank for its upcoming Hyperbola-3 (SQX-3) reusable rocket.

Yet, setting aside their track record with the solid-fueled SQX-1, i-Space’s pace on SQX-3 looks increasingly sluggish. Compared to peers like LANDSPACE, SPACE-PIONEER, and GALACTIC-ENERGY over the past two years, we’ve seen remarkably few updates on integrated flight hardware or major engine hot-fires—mostly just isolated tests on support hardware.

i-Space has completed static structural load testing on the interstage and aft thrust sections of its reusable Hyperbola-3. Spanning 4.2-meter diameter, these core primary structures were subjected to simulated worst-case ascent, 9-engine clustered thrust, grid-fin aerodynamic steering, and vertical landing touchdown loads.

- 直径4.2メートルの構造部に、上昇時や9基エンジンの推力、着陸時などを想定した荷重を加えた

- 一方、統合機体や主要エンジンの燃焼試験に関する進展が少なく、開発ペースは遅れ気味との指摘です
