    Abstract: An engine mount assembly for coupling an engine to an airframe includes a torsion bar, a lateral movement control assembly and a vertical movement control assembly. The torsion bar has a torsional stiffness and is coupled between the engine and the airframe such that torsional movement of the engine causes torsion in the torsion bar. The lateral movement control assembly has a lateral stiffness and is coupled between the torsion bar and the airframe such that lateral movement of the engine causes rotation of the torsion bar which reacts on lateral movement control assembly. The vertical movement control assembly has a vertical stiffness and is coupled between the engine and the airframe such that vertical movement of the engine reacts on the vertical movement control assembly. The engine mount assembly, thereby enables torsional, lateral and vertical movement of the engine to be independently controlled.

    Abstract: According to one embodiment, an empennage attachment system features an aft attachment mechanism and a forward attachment system. The aft attachment mechanism is configured to be coupled to a tail section of a body of an aircraft and to an empennage proximate to an aft spar of the empennage. The aft attachment mechanism defines a pitch axis such that the aft attachment mechanism allows the empennage to rotate about the pitch axis. The forward attachment system is configured to be coupled to the tail section of the body and to the empennage proximate to a forward spar of the empennage. The forward attachment system is configured to restrict rotation of the empennage about the pitch axis to an allowable range of motion.

    Abstract translation: 根据一个实施例，尾翼连接系统具有尾部附接机构和前向附接系统。 尾部附接机构被配置为联接到飞行器的主体的尾部部分和靠近尾翼的后翼梁的尾翼。 尾部附接机构限定俯仰轴线，使得后部附接机构允许尾翼围绕俯仰轴线旋转。 前向附接系统被配置为联接到身体的尾部和靠近尾翼的前翼的尾翼。 前向附接系统被配置为将尾翼围绕俯仰轴的旋转限制到允许的运动范围。
