JMR Advances Towards Flight Under Cover of Darkness

摘要

At the end of 2016, both Bell Helicopter and the Sikorsky-Boeing team gave brief glimpses under the veil of their Joint Multi-Role (JMR) technology demonstrators. The Bell V-280 Valor began engine-on testing in Amarillo, Texas, while the composite fuselage for the Boeing-Sikorsky SB>1 Defiant was delivered to Boeing's Mesa, Arizona, facility. Both companies are building aircraft that are slated to fly this year, but neither has released any photos since Fall 2016.
