Star Wars : EotE Minos
- No communication is allowed to a ship traveling in hyperspace, or a ship in hyperspace communicating to anything realspace
- while in hyperspace only mass shadows are able to be detected.
- tracking a vessel that jumps into hyperspace requires plotting its vector and comparing it to know routes.
- To jump into hyperspace a ship must be beyon the influence of gravitational forces
- Hyperdrive inhibitors prevent ships from running into mass shadows.
Hyperdrives are a vital starship engine system that allows vessels to enter hyperspace to traverse the vast distances of space at faster-than-lightspeed. The hyperdrive was thus a key technology in the foundation of galactic society, trade and war. The construction and working principle of a hyperdrive was based on Hyperdrive Theory. The term was used to describe the engine and all components required for its use, such as the hyperdrive motivator or hyperdrive field guide.
The hyperdrive allowed travelers to traverse the galaxy spanning over 120,000 light years from hours, days, and even months. the exact travel time depending on a number of factors including destination, point of origin, route, and class of hyperdrive. After the rise of the Empire, the technology was so developed that anyone with the fuel and a star ship could spend hours to nearby planets, Days to systems within a sector, weeks to another sector, and months to travel through regions of the Galaxy
The hyperdrive was generally built from a durable titanium alloy compounds specially designed to allow them to stand up against the continual stress caused by traveling between the dimensions of realspace and hyperspace.
Hyperspace was a separate dimension of space time that could only be entered at faster-then-light speeds. The process of entering hyperspace is known as a “Jump”. To launch a starship beyond lightspeed the hyperdrive made use of supralight hypermatter particles to create complex affect to make the jump without changing the ships configuration of mass and energy.
A pilot would enter the commands via a paralight system to start a complex reaction in the hyperdrive power plants to enter hyperspace. The hyderdrives used a field guide to collect gamma radiation and modify it in a fusion generator through kilometers of effect channels or looped superconducting wire. Then the hyperdrives boosters and ionization chambers would begin ignition in dampers and finally release energy causing ripples that would propel the ship into hyperspace. On reversion to real space from Hyperspace the same ripples would safely decelerate the ship and drop it out of hyperspace releasing Cronau radiation.
Safety was assured by inertial dampers to protect the ship and crew from the acceleration into hyperspace, and a null-quantum field would be generated around the ship to help stabilize the vessel. Shields protected the ship from gas, dust, and dark matter. As well as a tuned stasis field, stabilizers, and regulators.
A hyperdrive could only initiate a jump into hyperspace when reasonably free of of the gravitational pull of a major celestial body. Hyperdrives also included an inhibitor tied into the navigation computer that cut out the hyperdrive in the event of getting too close to a gravitational field or body, this was very risky to do, and would often result in the disappearance of the ship and all on board.
Since Hyperspace is an alternate dimension, no interaction is possible to realspace or vis versa except the detection of mass shadows. Ships traveling in hyperspace also cannot detect other ships due to the shielding and fields used to protect the ship. Often fleets of ships would slave to a single nav computer to coordinate jumps and would have a near perfect change of reverting in the same formation they started in.
Most space travel in the Galaxy takes place via “hyperlanes” that are well mapped out and have beacons activated to help update nav computers on any changes to the route. Tracking a ship that jumps into hyperspace is mostly about knowing their vector and plotting a course along the same route until it needs to revert and update the nav data.
When the U-wing jumps to hyperspace from Jedha it does so while in atmosphere, and under gravitational effects of the moon. If this is possible, there is no reason why it could be used as a method of evading blockades. The Millenium Falcon in ANH would never have had to avoid the Star Destroyer, the Rebel transports in ESB would have never needed the Ion cannon, the Naboo Queens’ ship would have never needed R2-D2 to become a hero and fix the ship while running a blockade.
In the Force awakens, Han Solo avoids a planetary shield by disabling the hyperdrive inhibitor to revert closer to the planet. To me this is possible, extremely risky, and only viable because it is han solo, it is the Millenium falcon, and its a writers fiat to move the story along.
