NASA飞行员瑞奇·罗杰斯:“一切都好……”

For NASA Wallops Flight Facility research pilot Rich Rogers, July 26 brought an end to one of the things in his life that he has greatly enjoyed – flying Navy and NASA aircraft. After a few quick laps around the Wallops airfield in the B200 King Air, Rogers settled the aircraft onto the runway and taxied to the hangar, along the way receiving a water cannon salute from the Wallops Fire Department. This brought his 39 year combined Navy and NASA flying career to an end. Rogers has spent the last 29 years flying for NASA’s Wallops Flight Facility as a research pilot, a career that took him on airborne science missions around the world. This image shows Rogers in the cockpit, flying a T34…

用无人机看世界

A drone moves high above downtown Reno, Nevada, on the afternoon of June 23, 2019 as part of NASA’s TCL-4 (Technology Capability Level) operation. TCL-4 involves flight testing multiple UAS (Unmanned Aerial Systems) in higher-density urban areas for tasks such as newsgathering, package delivery and large-scale contingency mitigation. The next and final test site will be Corpus Christi, Texas in August. The challenges associated with the safe flight of drones – piloted or unpiloted – are a big topic at EAA AirVenture in Oshkosh, Wisconsin, going on now through July 28. NASA researchers are at the show talking to thousands of general aviation pilots and aviation enthusiasts about how NASA, with its partners including the FAA, has created a game plan to address the biggest…

随着X-57 Mod II初具规模,标志着全电动飞机发展的新里程碑

随着X-57 Mod II初具规模,标志着全电动飞机发展的新里程碑

作为综合旋转测试的一部分,X-57 Mod II全电动飞机的电动机和螺旋桨将首次通电并一起旋转。Scaled Composites的项目工程师克里斯•希格比(Chris Higbee)出现在Mod II型飞机的驾驶舱里。背景中沿着山坡看到的风力涡轮机展现了全电动飞机未来的景象,未来X-57的最终阶段被称为Mod IV,它的机翼将集成12个发动机舱,最终将容纳12个小型电动高扬程电机和螺旋桨。 The electric motors for X-57’s Mod II vehicle and their propellers were powered up and spun together for the first time as part of an integrated spin test. Chris Higbee, Project Engineer at Scaled Composites, is seen in the cockpit of the Mod II vehicle, which is the aircraft’s first of three electric configurations. The wind turbines seen along the hillside in the background illustrate an impression of the future final phase of X-57, known as Mod IV, which will feature 12 small electric high-lift motors and propellers along its wing.
