Question 47
AOptions
BSolution
'Greased Lightning-10 (GL-10)' was an experimental unmanned aerial vehicle (UAV) developed and tested by NASA. Its unique feature was its ability to take off and land vertically like a helicopter but fly efficiently like a plane. This design, known as a 'tilt-wing' aircraft, was battery-powered, making it an electric plane. The GL-10 project aimed to test the feasibility and efficiency of electric propulsion for future aircraft designs, particularly for quieter and more fuel-efficient vertical take-off and landing (VTOL) vehicles.
CStrategy
For questions on recent technological innovations or projects, identify the key organization involved (e.g., NASA, ISRO) and the core technology or purpose of the project. Understanding the 'what' and 'who' behind the innovation is usually sufficient.
DSyllabus Analysis
This question falls under Science and Technology, specifically current affairs related to aerospace technology and new developments in aviation.
EQuestion Analysis
Easy. GL-10 was a prominent news item in the field of aerospace innovation at the time, particularly given NASA's involvement.
