Delayed Reaction Drive

​A Delayed Reaction Drive (DRD) is a prototype propulsion system undergoing current development.  With over two decades of research and experimentation, it has reached the crossover point from concept and into reality.

Through the proper application of Hermetic Principles to Classical Newtonian Physics, the harmonics of electro-mechanical movements of a DRD are tuned in a manner that delays the propagation of the reactive force. The result is a series of incremental movements or pulsed translations.  A DRD will not significantly increase the velocity of an object in low gravity environments (outer space) but it will shift their direction or bring them to a stop.

Why is this significant?  It means that unlimited maneuvers (such as yaw, pitch and roll) in space can be performed without the need to eject mass, release propellent or burn fuel.  The only energy requirement is the use of electricity provided by photovoltaics (the unlimited supply of sunlight).

​

The very fact that DRDs function without relying on stored combustible chemical fuels or the ejection of propellant (ionized or liquified) required by traditional thruster systems is paramount.  For it means that required combustion fuels and propellants can be better reserved for increasing an object’s velocity in space, not wasted on decreasing it or for performing micro-maneuvers.  Since DRDs only require electrical current, they have the potential to be used indefinitely during a space vehicle’s service life.  Operating DRDs as “Space Steppers” or “Space Brakes” alone or in tandem with traditional thruster systems on interplanetary vehicles would be tremendously advantageous for certain missions in terms of: 1) fuel conservation; 2) reduction of vehicle mass; 3) extending mission durations; and, 4) cost savings.  The conceptual DRD shown in the lower video link has a mass of about only 200 grams, which makes their miniature profile suitable for use on CubeSats.

​

​A DRD can be used to: 1) orient the position of space stations; 2) maintain distancing in CubeSat arrays; 3) induce micromovements during docking; 4) capture stray satellites; and, 5) relocate asteroidal drilling and mining equipment.  It also has the potential to reduce the kinetic energy and change the orbits of asteroids and comets on a collision course with Earth, thus helping to avoid a mass extinction event.
