Featuring Curtis Smith on Drums and Percussion. Please review the notes below and try harder. I still believe in the mission but must recognize certain deficiencies in production.
General Principles for the Successful
Design and Manufacture of
an EmDrive Thruster
1.Design the cavity for the required operating frequency and mode,
at a specified temperature.
2. The design should aim for a clear separation of operating frequency and mode from the various possible modes. A series of designs should be undertaken as part of a full model analysis. The opera
ting mode must remain above cutoff.
3.For a narrow band microwave source, the cavity geometry should include shaped end plates to ensure that wave
- front phase distortion, which results ina bandwidth spread, does not limit the Q of the cavity.
4. The cavity design should be initially tested with a swept frequency to identify the resonant
frequencies of the required mode and adjacent modes. A successful design and build will
give an initial resonant frequency within a maximum of 0.5% of design value
5.Cavity manufacture to high tolerance is essential to obtain high Q at the specified resonant
frequency. Manufacturing tolerance should be around ±0.01mm
6. Assembly of the cavity must include an end plate alignment process to obtain a Q of at least 50,000. Low Q
values are unlikely to give predicted thrust values, as they are a sign of poor
design or manufacture.
7.Whatever input circuit is used, loop, slot, dipole etc., it must be designed and tested to
deliver a match between the wave impedance of the cavity at the input point and the microwave source impedance. Input tuning is inevitably a sensitive and lengthy adjustment
process.
8. A correctly matched input circuit will give a loaded Q value of half that of the natural unloaded Q. Optimum match can be checked by measuring internal cavity power using a small detector probe positioned at E field maximum. The probes hould be designed to give an output at least 20dB down on input power to avoid loading the cavity.
9. Thrust measurement requires a clear understanding of Newtonian principles, as applied to a
propellantless thruster. Expecting to measure thrust as if EmDrive is a conventional
propulsion system will lead to ambiguous results. Ideally,thrust should be measured by
measuring the acceleration of a freely suspended thruster,and
then applying Newton’s laws.
10. Synthetic wave frequencies can one day power us to distant stars but this will not be achieved without a clear understanding of frequency and amplitude modulation over desired duration to create a reference unit, hereto known as the "track", and submitting at the precise time and predetermined rate of 1/week. Results are to be improved through simultaneous propagation across 200 to 300 end points to create a multiplier effect known as "The Weekly Beat"
