Mobile engine propulsion system?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of a mobile engine propulsion system featuring four engines positioned at the corners of a fuselage, capable of rotating to provide propulsion and deceleration. The conversation touches on the practicality of such a design, referencing its portrayal in popular media and exploring its potential applications in aviation.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests that a system with rotating engines could enhance maneuverability, similar to helicopters.
  • Another participant acknowledges the possibility but emphasizes the engineering and material challenges involved, referencing the Osprey as a related example.
  • A different viewpoint mentions that while the concept is common in discussions about flying cars, such designs have not been realized commercially due to economic feasibility issues.
  • One participant expresses skepticism about the concept, citing numerous drawbacks such as noise, inefficiency, danger, and instability, while also humorously suggesting an alternative method of propulsion involving manipulation of Earth's magnetic fields.

Areas of Agreement / Disagreement

Participants do not reach a consensus; there are multiple competing views regarding the feasibility and practicality of the proposed propulsion system, with some expressing optimism and others highlighting significant challenges and drawbacks.

Contextual Notes

Limitations include unresolved questions about the engineering requirements, material capabilities, and economic viability of the proposed system. The discussion also reflects a mix of speculative ideas and practical concerns.

would it be possible to have a system that has 4 engines on the corners of a 'fuselage' and these engines can rotate about joints giving the plane propulsion and deceleration. also this helps the pilot manipulate tha plane a lot easier (sort of like a helicopter).

NOTE: these are like the planes that they have in terminator 4. Is it possible to actually recreate those.

Sure, but the engineering and materials for such a creation is the hard part. Look at the Ospray. We really need annother Howard Hughes.
 
loud, inefficient, dangerous, unstable... there are a million reasons that invention will never see the light of day.

Now if only we could move about by manipulating the magnetic fields of the Earth like the gray aliens do...
