Zusammenfassung:To provide a system and method for forming an enclosure around an APU to protect an airframe from thermal effects of a thermal event and maintain an enclosure for a thermal suppression system, without increasing the weight, cost and production time of the aircraft.SOLUTION: An auxiliary power unit enclosure of an aircraft includes a space frame configured to carry a load and defining an auxiliary power unit compartment. The space frame includes a plurality of frame elements coupled together at a plurality of nodes. The auxiliary power unit enclosure also includes a fairing coupled to and surrounding the space frame.SELECTED DRAWING: Figure 4 【課題】熱イベントの熱効果から機体を保護し、熱抑制システム向けの囲いを維持するために、ＡＰＵの周りに囲いを形成することにおいて、航空機の重量、費用、及び製造時間を増加させることのないシステム及び方法を提供する。【解決手段】航空機の補助動力装置の囲いが、荷重を支え運ぶように構成され且つ補助動力装置コンパートメントを画定する立体骨組みを含む。立体骨組みは、複数のノードで共に連結された複数の骨組み要素を含む。補助動力装置の囲いは、立体骨組みに連結され且つ立体骨組みを取り囲むフェアリングも含む。【選択図】図４
