NTSB says FedEx plane with a disabled landing gear had suffered a leak of hydraulic fluid_我的网站
一 | 8 月 25 日消息，三星是全球研发投入最为激进的企业之一。今年上半年，这家韩国企业的研发支出已经超过 27.36 万亿韩元（注：现汇率约合 1,326.96 亿元人民币），同时其全球专利总量也即将突破 30 万件。 Investigators said Friday they found hydraulic fluid leaking from a hose in the landing gear system of a FedEx plane that was forced to make an emergency landing this month in Chattanooga, Tennessee.The National Transportation Safety Board said that investigators also found a “discontinuity” in the wiring of an alternate system for lowering the landing gear.Video captured by emergency responders showed sparks flying after the Boeing 757 touched down on Oct. 4 with the left landing gear not fully extended. The plane ran off the end of the runway, but none of the three crew members were injured.The pilots reported that after taking off from Chattanooga, they got a warning about low fluid level and a lack of pressure in one of the hydraulic systems, and they decided to return to the airport. After getting an alert about the landing gear, the pilots declared an emergency. They did a low fly-by that allowed people in the airport tower to confirm that the left landing gear was not extended. The pilots circled and landed with the crippled gear. They were able to keep the plane going straight but couldn't stop until 830 feet beyond the end of the runway, the NTSB said in a preliminary report. Pilots used a slide to get out of the plane.The NTSB said an examination showed that a hose tied to a component used to activate the landing gear was leaking hydraulic fluid.The NTSB said it is continuing to investigate the incident.。据 JoongAng Economy News 报道，三星电子目前在全球拥有 296,468 项专利，距离 30 万件这一重要里程碑仅一步之遥。
二 | 今年上半年，三星新申请的专利数量也创下历史新高，在韩国、美国以及其他地区共申请了 11,054 项新专利，其中韩国申请 5,572 项，美国申请 5,482 项。从三星目前有效的专利数量来看，美国占据最大份额，其后依次为韩国、欧洲、中国和日本。美国：109,674 项韩国：69,831 项欧洲：55,319 项中国：32,678 项日本：8,025 项其他地区：20,941 项三星今年上半年的研发支出同比 2025 年同期大幅增长 51.5%，创下公司单个半年周期研发投入的历史最高纪录。据报道，这种激进的研发投入与三星电子执行董事长李在镕对长期技术竞争力的重视有关。三星希望通过持续加大研发投入，巩固自身技术优势，并在与竞争对手的长期竞争中占据领先地位。
