During this "cold motor" test, DM-2's overall temperature will be lowered to 40 degrees Fahrenheit to validate the motor's performance in cold weather.
These new materials will allow for the elimination of joint heaters that were necessary in the original 4-segment motor design. This will save significant weight, further reduce system complexity and simplify launch operations, while simultaneously delivering increased operating margins at lower ambient temperatures,” noted ATK
... Die neuen Materialien (in den Dichtungen) werden es ermöglichen Wärmeelemente an den Verbindungen (der Segmente) zu eleminieren und so deutlich Gewicht zu sparen, die Komplexität reduzieren, Prozeduren vereinfachen und mehr Spielraum bei niedrigen Temperaturen geben.
The motor is potentially transferable to future heavy-lift launch vehicle designs.
