A stowable propulsion device for a marine vessel. A base is configured to be coupled to the marine vessel. A propulsor is configured to propel the marine vessel in water. An arm pivotably couples the propulsor to the base such that the propulsor is movable into and between a stowed position and a deployed position, where the propulsor is closer to the base in the stowed position than in the deployed position. A first actuator pivots the arm so as to move the propulsor into and between the stowed position and the deployed position. A second actuator is manually actuatable to pivot the arm so as to move the propulsor towards the stowed position.

An improved aircraft engine stand is disclosed, which comprises a cradle comprising a cradle frame having first and second frame load transfer openings, first and second arm assemblies secured to the cradle frame and having first and second arm load transfer openings, and first and second load transfer pins shaped to be received in the load transfer openings. The frame load transfer openings can be aligned with the arm load transfer openings such that when the each load transfer pin is inserted into both a frame load transfer opening and an arm load transfer opening, lateral and axial loads placed on the arm assembly are transferred to the cradle frame.

A hybrid turbomachine enclosure includes a plurality of walls interconnected to form an interior configured and disposed to receive a turbomachine, the plurality of walls including a first wall having a panel on frame construction and a hybrid wall including a first portion having a panel on frame structure and a second portion having a stiffened frame panel structure.

A molded housing for a machine includes a shaft, a first region, a second region, and a third region, a first passage for the shaft and a second passage. The first passage includes a first molded edge and the second passage includes a second molded edge. The second passage includes a reinforcement element running from a first connection point connected to the second molded edge to an opposite second connection point connected to the second molded edge. The second molded edge includes a first securing device at a third connection point and a second securing device at a fourth connection point. The second passage has an opening in a wall of the molded housing and a projection of an imaginary line connecting the third connection point to the fourth connection point into the opening intersects a projection of the reinforcement element into the opening at an acute angle.

A base structure of a cooling fan and a manufacturing method of the base structure are provided. The base structure includes a bearing, a shaft sleeve and a base. The bearing defines therein a first cylindrical cavity for receiving a shaft of the cooling fan. The shaft sleeve is made of a first material and defines therein a second cylindrical cavity. The shaft sleeve includes a protrusion part and a first engagement structure arranged at a first end and a second end of the shaft sleeve, respectively. The base is made of a second material and includes a second engagement structure. The second engagement structure is interlocked with the first engagement structure since the second engagement structure is integrally formed with the base. The first material has a greater rigidity than the second material.

In a generator in which a stator is fixed to a housing which includes a first bracket having a bearing portion for pivotally supporting one end portion of a rotary shaft, and a second bracket covering a cooling fan that rotates with the rotary shaft, and a rotor surrounded by the stator is fixed to the rotary shaft, the stator is fixed to the first bracket, and the first bracket is integrally provided with a tubular portion which surrounds the stator for permitting cooling air sucked in by the cooling fan to flow between the tubular portion and an outer periphery of the stator, and the second bracket is connected to the tubular portion. Accordingly, cost is reduced by connecting first and second brackets together without using long through-bolts, and efficiency of cooling the stator is enhanced by making the cooling air flow along the outer periphery of the stator.
