PROBLEM TO BE SOLVED: To provide a system for sound insulation and impact protection from an open rotor engine.SOLUTION: An aircraft (100) includes: a fuselage (102) including a nose (104), a tail (106), a hollow, and an elongate body (108) extending therebetween; a wing (110) extending laterally away from the fuselage, the wing including a leading edge (114) in a direction (116) of motion of the aircraft during normal flight and a trailing edge (118) on an opposing edge of the wing, and an engine (120) configured to drive a bladed rotatable member (122), the engine coupled to at least one of the wing and the fuselage. The aircraft further includes at least one of a forward chine member (123), which extends from the fuselage at a point (124) forward of the engine aftward to a point (128) aft of the bladed rotatable member, and an aft chine member (132), which extends from a point (134) to a point (138).SELECTED DRAWING: Figure 1 【課題】オープンロータエンジンからの防音、衝撃防護システムを提供する。【解決手段】飛行機（１００）は、機首（１０４）と、機尾（１０６）と、中空部と、それらの間に延びる細長本体（１０８）とを含む胴体（１０２）と、胴体から横方向に延びる翼（１１０）で、通常飛行中は飛行機の動く方向（１１６）に前縁（１１４）と、翼の反対縁に後縁（１１８）を含む翼と、動翼付回転可能部材（１２２）を駆動するよう構成されたエンジン（１２０）で、翼及び胴体のうち少なくともひとつに結合する前記エンジンと、を含む。飛行機はさらに、エンジンの前方の点（１２４）で胴体から後方に、前記動翼付回転可能部材の後方の点（１２８）まで延びる、前方尾根部（１２３）及び点（１３４）から点（１３８）まで延びる後方尾根部（１３２）の少なくともひとつを含む。【選択図】図１
