From point 1 to point 2 the propellant mass is pinned against the end of the tract by centrifugal force. To answer your question the efficiency is about the same as an EDF as far a static thrust goes but the inefficient airflow path means the thrust will fall away as the plane speed increases. On 8/25/2017 at 12:01 AM, AbnormallyHonest said: If you had a rotating body generating large amounts of centrifugal inertia, but used electromagnets to balance the centripetal force, You don't "balance" the centripetal force. This is an essential requirement in marine propulsion or wherever the load can drive back, as in centrifugal pumps. "The enlisted men get to go out and shovel whatever they can find into the propellant tanks" Hydrogen gives the best exhaust velocity, but the other propellants are given in the table since a spacecraft may be forced to re-fuel on whatever working fluids are available locally (what Jerry Pournelle calls "Wilderness re-fuelling", Robert Zubrin calls "In-situ Resource Utilization", and I … With an EDF the thrust can actually increase with speed.

Posted August 25, 2017. The rotor has an aperture therein which is substantially larger than the shaft, such that the rotor is able to rotate at speed away from the shaft, as well as move longitudinally perpendicular to the axis of rotation. One important engineering problem consists of accurately tracking the position of the projectiles and rotors and guiding each projectile exactly onto … $\begingroup$ "If the two forces (centrifugal from our rotation and propulsive from our engines) are kept at exactly the 90° angle, they're non-interactive and the extreme ends of the wheel would keep exactly the same distance to each other as if the engines were off. An excellent recent survey of this area is given in Ref.40. In the late 1970s, Robert Cook, a US inventor, patented an engine that supposedly converted centrifugal force into linear motion. The mechanism has a pair of counter rotating masses which are subjected to centrifugal forces. Because brake disk quality is directly related to driving safety, … This is an essential requirement in marine propulsion or wherever the load can drive back, as in centrifugal pumps.
