XCOR Aerospace has issued the initial phase of a two-phase contract to ATK's Aerospace Structures Division for the detailed design and manufacture of the Lynx Mark I suborbital reusable launch vehicle (RLV) wings and control surfaces. The initial wing and control surface design has been developed by XCOR to rigorous design standards to enable the craft to perform tens of thousands of flights to and from suborbital altitudes exceeding 100 km. ATK will create a detailed design ready for manufacture, working with structural and flutter analysis experts from Quartus Engineering in San Diego, CA. The wings will be installed on the Lynx Mark I, which is the prototype of the Lynx family of suborbital RLVs from XCOR; the production models are called Lynx Mark II.
