Sea Cavalry SD-40 design and features

“海上骑兵”SD-40的设计和特点

 

Sea Cavalry SD-40 VTOL aircraft offers long-range endurance and high-speed capabilities. It adheres to water and salt-proofing standards and ensures strong resistance to wind.

“海上骑兵”SD-40垂直起降飞机具有远程续航能力和高速能力。它符合防水和防盐标准，并确保具有很强的抗风能力。

 

The aircraft features a triple fuselage structure with two pod-like structures integrating the wings on both sides of the main fuselage. The rear sections of the pods are connected by a modified twin tail boom.

这架飞机的特点是一个三机身结构和两个豆荚状结构，整合了主机身两侧的机翼。吊舱的后部部分由一个改进的双尾臂连接。

 

Vertical lift for the unmanned aircraft is ensured by eight twin-blade propellers fitted to the forward and rear sections of the fuselage support structures. Positioned above and below the support structures at four locations, the propellers act as vertical thrusters to enable the UAV to perform take-off, hover, and control landings.

无人机的垂直升力由安装在机身支撑结构前部和后部的八个双叶螺旋桨确保。螺旋桨位于四个位置的支撑结构上方和下方，用作垂直推进器，使无人机能够执行起飞、悬停和控制着陆。

 

Sea Cavalry SD-40 features a pusher propeller attached to the rear of the main fuselage. The pusher propeller is driven by the main engine of the aircraft, while eight small propellers are driven by small electric motors.

“海上骑兵”SD-40的特点是在主机身后部安装了一个推进器。推进器由飞机的主发动机驱动，而八个小型螺旋桨由小型电动机驱动。

 

The main fuselage features four struts/brackets, which act as landing gear. The UAV can take-off and land from the deck of warships, aircraft carriers, and destroyers.

主机身有四个支柱/支架，用作起落架。无人机可以从军舰、航空母舰和驱逐舰的甲板上起飞和降落。

 

Sea Cavalry SD-40 has a length of 2m, a wingspan of 3.7m, and maximum take-off weight (MTOW) of 40kg.

“海上骑兵”SD-40机长2米，翼展3.7米，最大起飞重量40公斤。

 

Sea Cavalry SD-40 payload details
