Here is how NASA determines crucial aircraft characteristics such as lift and drag.

Except for its prowess, NASA is also well known due to its willingness, capacity to be involved in the most sophisticated, amazing and stunning projects. Today, Connectikpeople is thrilled to help you discover how researchers at NASA's Langley Research Center use all sorts of tools and techniques to learn more during the development of aircraft and spacecraft designs. In this photo, engineers led by

researcher Greg Gatlin have sprayed fluorescent oil on a 5.8 percent scale model of a futuristic hybrid wing body during tests in the 14 by-22-Foot Subsonic Wind Tunnel.

Connectikpeople has observed that, the oil helps researchers "see" the flow patterns when air passes over and around the model. Those patterns are important in determining crucial aircraft characteristics such as lift and drag.
