Problems solved by technology

[0003] At present, there are similar mechanisms on more mature helicopters in China, but the structure is relatively complicated, especially in the secondary protection of the locking mechanism.
At the same time, limited by the mechanism, most locking mechanisms have an impact on the aerodynamic shape of the fairing, so these effects need to be improved

Abstract

The invention belongs to the field of aircraft radome systems and relates to an improvement for a locking mechanism of an engine compartment radome system. The locking mechanism comprises a lock support assembly and a lock assembly, wherein the lock support assembly comprises a lock support 1, a clamp ring support, a clamp ring and a fastening assembly; and the lock assembly comprises a rubber stop block, a -shaped piece, a safety cap, a pull ring, an adjustable lock, a rubber block, a safety cap spring, a shaft, a U-shaped piece and fastening assemblies. When the locking mechanism is mounted, the lock assembly is in bolted connection with a radome, the lock support assembly is fixed on a platform with rivet. The lock support assembly and the lock assembly can fix the radome through matching of the clamp ring, the rubber stop block, the protective cap, the adjustable lock and other assemblies, so that a locking function is realized. The locking mechanism can fasten the radome and can provide secondary protection for the assemblies of the radome; the exchange among different batches of radomes can be met by adjusting the locking mechanism; and in addition, the shape of the locking mechanism is smooth, thereby realizing a rectifying effect.

Description

technical field [0001] The invention belongs to the field of helicopter fairing systems and relates to the improvement of the locking mechanism of the helicopter power cabin fairing. Background technique [0002] The main function of the locking device is to fix the fairing of the power cabin so that it forms a stable structure to protect various equipment in the power cabin. [0003] At present, there are similar mechanisms on more mature helicopters in China, but the structure is relatively complicated, especially in the secondary protection of the locking mechanism. At the same time, limited by the mechanism, most of the locking mechanisms have influence on the aerodynamic shape of the fairing, so these influences need to be improved. Contents of the invention [0004] The purpose of the present invention is to propose a new type of locking mechanism, which is installed on the fairing of the power cabin to meet the requirements of the fairing system on the secondary pr...
