Propulsion System Efficiency Optimization through Dilithium Crystal re-alignment.


  • In order to meet the increasing needs of propulsive efficiency with low impact to the warp thrust specific fuel consumption, new methods to increase passive energy to the warp propulsion system have been in development by the ASDB Advanced Propulsion Division. Special grants were given to Yoyodyne Propulsion Systems, Utopia Planitia Fleet Yards, and San Francisco Fleet Yards to perform field benchmark tests and upgrade performance checks of these new methods. These new methods will be implemented as standard operating procedures and processes in the next generation vessels.

Dilithium Crystal Realignment Procedure and Results

  • The first major achievement of these passive energy optimization methods is done through a realignment of the Dilithium Crystal in the Matter Antimatter Reaction Assembly (M/ARA). A simple increase in the delta angle of the crystal surfaces that experience the incoming matter and antimatter stream flows shows a cleaner reaction and more efficient mixing of streams giving a 0.75% increase to the M/ARA efficiency providing 99.9965% efficiency to the latest assemblies in the field and 99.9845% to older models. A prototype next generation M/ARA shows 99.999% efficiency, almost perfect mixing. Power output has shown an average increase of 35% with a deviation of 10% based on hardware. These adjustments come with a price. A heightened recrystallization schedule must be implemented on current starships in the recrystallization subroutine. If not implemented a slow exponential decrease with time in performance is shown to be 0.0125% per rotation schedule interval. To maintain efficiency in (M/ARA) without a recrystallization schedule impact, tests show that for all vessels the crystal delta must be increased at a faster schedule of every 0.8 months or every 0.8 regeneration cycles. Next generation ships will have the new program as a standard part of the subroutine.

Optimized Methods and Procedures to Enhance Dilithium Crystal Realignment

  • Simulations and field tests show a decoupling of the crystal delta angle to the matter/antimatter injection angles in the core. As such, methods to enhance the passive energy effect to the propulsion systems with more active processes were developed. To optimize performance of the overall propulsion system a flow decrease and injector angle alignment change is recommended. Hardware specific recommendations can be seen in Appendix A of this report. With these methods impemented, field test show the average Specific Fuel Consumption (SFC) to decrease by 17.5% with a deviation of 2.5%. Warp Thrust Specific Fuel Consumption (WTSFC) shows an 8.5% decrease with a 1.5% deviation.
  • For specific physical changes needed to be done to the system for different class vessels see Table 1.0. For results to the system by applying changes prescribed in Table 1.0 see Table 1.1.

  • Figure 1.0 shows that the Dilithium Crystal delta, the realignment angle, is the angle formed from a vector normal to the surface of the crystal surface to the vector across its surface.

  • Table 1.0 shows that for different starship classes, the physical parameters have to be changed by the prescribed amount to get the desired output shown in Table 1.1. For example, for an Akira-class starship the dilithium crystal delta angle should be realigned by 0.5 degrees, the matter flow rate into the warp core decreased by 0.36%, the antimatter flow rate into the core decreased by 0.639% and the injection of both matter and antimatter by 0.139 degrees to get the following improvements to the system. The matter-antimatter reaction will produce a 36% increase to the power output. This could result in a possible increase to warp speed or a power surplus to the ship. The matter and antimatter fuel consumption (SFC) will decrease by approximately 18% which will increase time intervals to refill the matter and antimatter pods. This will also decrease the fuel required to reach a certain warp speed (WSFC) by 8.65%. This means that the fuel required to reach each speed will be reduced by 8.65%.
