MEGA Drive Propulsion Experiments
Dr. James Woodward demonstrates experimental testing with the Mach Effect Gravity Assist (MEGA) drive using a 150g device and an 885g support structure. Woodward’s team used a Logitech Trio to record device motion, a Picoscope to capture position, voltage, and strain gauge data (0.3mm thick), and conducted tests with varying sweep rates (initially 1kHz, then planned for 500Hz) to identify resonance (expected around 35kHz).
The experiment highlighted the importance of single-variable testing (following Drew Rigma’s advice) and showcased a sophisticated, computer-controlled setup with integrated video recording. Challenges encountered included device rotation (attributed to sleeves), air-pumping effects (mitigated with baffles), a lost Picoscope file, and slow vacuum pump operation due to a previous power outage causing damage.
Woodward discussed future improvements, including vacuum system upgrades (potentially involving Mark Sokol and Andrew Aurigema’s equipment), material sourcing, and amplifier development (David’s and potentially Curvace’s). The collaborative nature of the research and the mutual reliance within the small scientific community were emphasized.
Experimental Setup and Methodology:
The core of the experiment involved precisely measuring the resonant frequency of a small device. The setup was remarkably sophisticated, incorporating:
- High-Resolution Video Recording: A Logitech Trio device captured the motion of both the test device and its support structure, allowing for detailed visual analysis of vibrations. Two dots tracked the movement, providing crucial data points. The video recording, coupled with comprehensive data logging, represents a significant advancement over older methods.
- Precise Data Acquisition: A Picoscope was used to record device position (red trace), applied voltage (blue trace), and strain gauge data (green trace). The strain gauge, a mere 0.3mm thick, provided critical information about the device’s response to the applied voltage. The data included a Fast Fourier Transform (FFT) analysis, revealing harmonic content and phases.
- Controlled Testing: The experiment followed a rigorous single-variable testing approach, a testament to the researchers’ commitment to accuracy and effective troubleshooting. This approach, echoing the advice of Drew Rigma, ensured that any observed effects could be directly attributed to the manipulated variable. Initial tests involved a 1kHz sweep rate from 45kHz to 25kHz, repeated over 20 seconds, with subsequent tests planned at a 500Hz sweep rate. Resonance was expected around 35kHz.
- Integrated Computer Control: The entire experiment was controlled and monitored via a centralized computer system, streamlining the process and ensuring seamless data acquisition and video recording. This centralized approach significantly improved documentation compared to older methods.
Challenges and Solutions:
The experiment wasn’t without its challenges. Initial observations revealed device rotation, attributed to sleeves added to prevent short-circuiting. The team also encountered issues related to the air-pumping effect, initially overlooked but later addressed by adding baffles. A power outage a week and a half prior caused significant complications, slowing down the vacuum pump (1402) and necessitating repairs. This highlighted the importance of robust equipment and contingency planning. Further challenges included the loss of a Picoscope file and the need for improved vacuum chamber design, specifically addressing the placement of the triple pump and the need for a new back plate. Material selection for the back plate proved challenging, with the need to balance functionality and aesthetics.
Collaboration and Future Directions:
The experiment highlighted the collaborative nature of scientific research. The team leveraged the expertise and resources of Mark Sokol and Drew, seeking assistance with equipment and materials. The discussion also touched upon the potential for collaboration with David Chester, whose amplifier (currently three years in development) and expertise in controls and feedback could significantly benefit future experiments. The team also discussed the need for improved materials to demonstrate Newton’s laws of force from watts of input.
Conclusion:
This detailed account of a high-frequency resonance testing experiment showcases the meticulous planning, precise execution, and collaborative spirit essential for successful scientific endeavors. The experiment’s rigorous methodology, coupled with the advanced data acquisition and analysis techniques, provides valuable insights into the behavior of the tested device. The challenges encountered and the solutions implemented underscore the importance of adaptability and resourcefulness in scientific research. The ongoing collaboration within the scientific community promises further advancements and exciting discoveries in the future.
