Graviman & Slowrotor
Mart, there might be reasons to worry about the X2's future.
Initially, five proposed configurations were funded for 'Joint Heavy Lift' program evaluation. It then got reduced to following three.
- Heavy quad-tilt-rotor from Bell-Boeing
- Optimum Speed Tilt-Rotor technology pursued by Karem and Lockheed Martin
- JHL - Sikorsky's X2 technology
.
There is an article in the new issue of AHS's Vertiflite on the JHL program. This article says that the door has been opened for Sikorsky's Variable Diameter Tilt Rotor to now be included in the ongoing configuration evaluations.
