A seaplane strut structure

Abstract

The invention belongs to the airframe structure and interior design technology, and relates to a strut structure of a seaplane. Including the front strut (1) and the rear strut (2); the present invention takes into account the bearing capacity of the fuselage structure and the need to overcome the overturning moment when the seaplane takes off, landed and parked on the water, and is designed as a double-beam type The strut structure forms multiple stable triangles in space. The front support is selected at 70% of the length of the front of the buoy's broken step, and the rear support is selected at the position near the buoy's broken step to minimize the additional bending moment when the buoy hits the water. The strut has a simple structure, direct force transmission, good manufacturability and easy processing. The buoys of the target type can be quickly installed on the CCAR23 land-based aircraft.

Description

Technical field [0001] The present invention belongs to the airframe structure and interior design techniques, relates to a seaplane strut structure. Background [0002] Seaplanes can take off and land using natural waters, and their uses are very extensive, and they have great potential for development in the military and civilian fields. China is rich in water resources, the current seaplane in the Bohai Sea, yangtze river delta and pearl river basin has broad application prospects, but the new research seaplane cost is high, the cycle is long, from land-based aircraft to seaplane has become a research trend, there is no mature CCAR23 land-based aircraft to install pontoons to change the successful precedent of seaplane, it is necessary to improve the substructure of the land-based fuselage, to achieve the land-based aircraft to install target pontoons, to meet the requirements of aircraft seaplane operations.

Problems solved by technology

my country is rich in water resources. At present, seaplanes have broad application prospects in the Bohai Sea, the Yangtze River Delta and the Pearl River Delta. However, the cost of newly developed seaplanes is high and the cycle is long. It has become a research trend to change from land-based aircraft to seaplanes. There is no domestic The mature CCAR23 land-based aircraft is a successful precedent of adding buoys to seaplanes. It is necessary to improve the lower structure of the land-based fuselage to realize the installation of target buoys on land-based aircraft to meet the requirements of aircraft water operations.
