Problems solved by technology

However, the trunnion-type support structure has the disadvantages that the distance between the supporting hanging points at both ends of the trunnion is small, and the stability of the RAT support is poor.
If the RAT support stability is increased by increasing the distance between the support points at both ends of the trunnion, the external dimensions of the trunnion and the support arm on the RAT rotation axis will be relatively large, resulting in large size and weight of the RAT support structure. question

Embodiment 1

[0027] Example 1. An ear-mounted support mechanism for a ram air turbine system, consisting of Figure 1-2 As shown, it includes a support arm, an adapter seat and a sealing structure. A fork-shaped structure is derived from the upper end of the RAT support arm, and a hole structure is set at the fork-shaped structure as the installation interface between the RAT and the aircraft. At the same time, the support arm and the adapter seat are provided with mutually independent high-pressure oil circuit and low-pressure oil circuit. The high and low pressure oil circuits of the support arm are connected.

[0028] High and low pressure intubations are arranged between the adapter base and the support arm for connecting the high and low pressure oil circuits between the support arm and the adapter base.

[0029] There are high and low pressure mounting seats on the outside of the oil circuit on both sides of the adapter seat, which are used to connect with the hydraulic oil circui...

Embodiment 2

[0035] Example 2. A ram air turbine system lug mount support mechanism, see figure 1 , The ram air turbine system hanger mounting support mechanism of the present invention includes a support arm 1, an adapter seat 4, a high-pressure intubation tube 15, a low-pressure intubation tube 3, a high-pressure mounting seat 11, a low-pressure mounting seat 9 and other parts. Wherein, a fork-shaped structure is derived from one end of the support arm 1, and a mounting hole is provided at the fork-shaped structure, which is used as a mechanical interface between the RAT and the aircraft.

[0036] When installing the RAT, align the axis of the mounting holes at the mounting lugs with the corresponding holes of the aircraft RAT mounting seat, and then insert the fixing screws to realize the fixing of the RAT. When the RAT is retracted, the RAT rotates around the axis of the mounting hole of the mounting ear to realize the rotation function of the RAT. In order to reduce the friction bet...

Embodiment 3

[0044] Example 3. An ear-mounted support mechanism for a ram air turbine system, consisting of Figure 1-2 As shown, it includes setting support arm 1, adapter seat 4, low-voltage mounting seat 9 and high-voltage mounting seat 11; wherein, the top of the support arm derives a fork-shaped structure, and the RAT mounting holes at the top of the two fork-shaped structures realize The connection with the aircraft structure; the adapter seat 4 is arranged between two forks; the adapter seat 4, the support arm 1, the low-pressure mounting seat 9 and the high-pressure mounting seat 11 are all provided with a low-pressure oil circuit and a high-pressure oil circuit. Connector 4, support arm 1, low-pressure mounting seat 9 and high-pressure mounting seat 11 are correspondingly connected to low and high-pressure oil passages, and adapter seat 4 is also respectively connected to low and high-pressure mounting seats in rotation, and the rotation axis is in line with that of the two forks....

Abstract

The invention discloses a hanging lug type mounting and supporting mechanism of a ram air turbine system. The device comprises a supporting arm (1), an adapter (4), a low-voltage mounting seat (9) and a high-voltage mounting seat (11), wherein a fork-shaped structure is derived from the top end of the supporting arm, and mounting holes are formed in the top ends of two branch forks of the fork-shaped structure, so that the connection with an aircraft structure is realized; the adapter (4) is arranged between the two branch forks; low-pressure oil ways and high-pressure oil ways are arranged in the adapter (4), the supporting arm (1), the low-pressure mounting seat (9) and the high-pressure mounting seat (11), the low-pressure oil ways and the high-pressure oil ways in the adapter (4), the supporting arm (1), the low-pressure mounting seat (9) and the high-pressure mounting seat (11) are correspondingly communicated, the adapter (4) is further rotationally connected with the low-pressure mounting seat and the high-pressure mounting seat respectively, and the rotating axis is coaxial with RAT mounting holes of the two branch forks. According to the invention, the problem of RAT installation in a narrow space on a machine is solved, and the stability of the RAT on the machine can be effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of aircraft emergency power systems, and in particular relates to an ear-mounted support mechanism for a ram air turbine system. Background technique [0002] The Ram Air Turbine System (RAT for short) is mainly used in the aircraft emergency power system to provide emergency energy for the aircraft. The RAT is usually recovered in the RAT cabin and is on standby. When the aircraft is in an emergency state, the turbine components are put into the airflow through the actuator, and the ram energy of the airflow is converted into emergency hydraulic energy / electrical energy for the emergency use of the aircraft. [0003] At present, the domestic ram air turbine system is mainly installed on the aircraft through frame plate and trunnion support. [0004] The frame-plate support structure is generally suitable for the RAT with the rear of the retractable actuator, and the frame-plate structure has a large shape...
