That's always been the distinctive difference between Imperial and Rebel fighters; Vader's was probably retconned to explain how he managed to get away from Yavin. That and shields.

Star Wars is basically fantasy, but I still find the Hey Wing too small for what it's supposed to be capable of.

Starwarships: Understanding the Role of CIS Star Fighters


Today we break down the role and purpose of each star fighters ship in the Confederacy of Independent Systems.

https://www.youtube.com/watch?v=nBOXBhHB6bM


1. Planetary defence forces with unique local manufactured fighters - sounds about right.

2. Territorial defence split cashew nut fighter - turret; tractor beam seems redundant.

3. Fan blade - not too sure on the stealth part; let's say it does make propulsion more efficient at the cost of being easier to hit, and the increased volume permits more weapon emplacements.

4. Vulture droid - wonder how much the walking tanks/boarding aspect costs?

5. Rogue fighter - Cylon Raider.

6. Umbarran fighter - we don't have viable energy shields, but we could place the cockpit on gimbals.

7. Hyena bomber - seems a better prospect than the Thai Bomber.

8. Droid trifghter - not too sure what advantage this design supposedly gives; gimballed cockpits might be beneficial to gravity bred pilots, who might still get disorientated despite artificial gravity.

Starwarships: Understanding the Role of Republic Star Fighters

Today we break down the role and purpose of each starfighters ship in the Galactic Republic Navy.

1. Ironically, dolphins make great pilots; presumably, navigators as well; they can also smell a trap.

2. Headhunter - probably should figure more prominently in the films due to availability and numbers, but that's retconning.

3. Aggressive Reconnaissance - rear gunner probably more useful as centralized turret; crew probably better composed of cheap specialists.

4. Torrent - folding wings, so aerospace fighters with aerofins could reduce volume, or increase it, by about five percent; one which makes them more compact and faster, the other would make them larger and slower.

5. Ann One -Ann for Anakin; space going variant of a pod racer.

6. Aethersprite - psionic powered jump drive, as well as sensor suite, at least in our iteration; the issue would be that you're going to be spending a week in hyperspace, and the ring would be more an easily slipped on drop tank that might have it's own refueling drone, so maybe thirty/seventy split, that would allow three weapon emplacements in the primary.

7. Actis - Drop in astrodroid mobile ship computer.

8. Vee Wing - probably better than the Thai Kiter.

Spaceships: Engineering and Planetary Environments

I wonder if fusion rockets or manoeuvre drives are carbon neutral or have other unforeseen environmental impacts?

Like local gravity fields going all wobbly.

In one of Niven's stories a fusion torch drive was used as a weapon to attack buildings.

A fusion drive in atmosphere will of course raise the temperature. Probably they don't change the composition of the atmosphere unless used to burn something. Probably.

Terraforming and full weather control are available around TL 12 so I think it's not a problem in Traveller. Traveller ships also don't have problems with heat management so planets should not either. Overheating is a significant issue for today's spacecraft as you can only radiate heat away, which is a slow process. Cooling fans don't work in vacuum. However, Traveller ships magically contain the heat of their fusion reactors.

To be honest the danger of climate change from sci-fi spacecraft engines seems less than the danger caused by a ship crashing on a planet with an atmosphere at orbital velocity.

One reason they encourage parking at the HiPort could be to minimize any possible impact.

Though it has me now thinking, exactly what happens directly under a vehicular gravitic motor, spaceship or otherwise? If it's a two hundred kay battleship, perhaps increased local gravity field.

1) Nothing unless you want the the GM to put reproductive health warnings on grav belts.

2) If using non-magical lift such as rotors or wings, the weight of the vehicle is supported by the ground as normal, but over a wider area as the air column spreads out. Basically if you have a closed van full of pidgeons, it weighs the same if they're roosting or flying. You will see variations as they flap, but it will average out the same.

Grav motors utilize technology that somehow interacts directly with the planetary gravitational field, so you have to wonder if it alters local gravity, specifically that underneath it, compared to manoeuvre thrusters that probably in the Mongosian variant pushers that recreate gravitational thrust independent of external gravitational wells.

Starwarships: Pasture or pasteurization, and Why Wasn't Orbital Bombardment Used More Often?

Orbital Bombardment is great! You don't have to risk any of your troops. You don't even need to step foot on a terrible planet like Kamino or Malachor or Philadelphia. Or so I thought... after doing a bit of research I've come to conclusion that orbital bombardment is not always the best choice.

Starwarships: The IMPERIAL Nebulon-B Frigate (Fan design)

The Nebulon-B has long been considered a Rebel vessel, but canonically this frigate was originally an Imperial vessel. I took on the challenge of creating what that might have looked like.

https://www.youtube.com/watch?v=Nz13rwQpUd4


It's an odd duck.

I always thought the design was optimized for modularization, which allowed a mix and match construction or easy reconfiguration.

The proposed stripped down aesthetic would fit that of the Why Fighters.

Spaceships: Why will Starship only have 2 rear fins?!

We’re less than a week away from this year’s Starship update from Elon Musk. And before the party gets started, we’re already catching some major changes happening before our eyes.

The most obvious change is the fact that Starship only has two finny / flappy / airbrakey things instead of three. Now the previous version touted just last year at the DearMoon event showed Starship sporting 3 fins that were also its landing legs.

So now that we’re seeing only two, the question has come up, why? Why two?

So today we’re going to do a really quick rundown on why two might be better than three, show you some potential problems with three fins, and then we’ll show you exactly how they’ll control their reentry and landing with just 2 rear fins.

https://www.youtube.com/watch?v=hsul-GE4XiA



1. Giant airbrakes or body flaps.

2. Weight, though not necessarily volume.

3. Landing legs; would need to be pre stressed. Or have springs.

4. For a tail sitter, you probably would prefer a vertical descent.

5. The belly flop seems a viable solution.

(Aero)spaceships: Engineering and Military anti gravity - Prof Simon

Does the B2 stealth bomber use anti gravity technology. Prof Simon asks questions and finds some answers.

https://www.youtube.com/watch?v=95DjBzwF2ZI



The Biefeld–Brown effect is an electrical phenomenon that produces an ionic wind that transfers its momentum to surrounding neutral particles. It describes a force observed on an asymmetric capacitor when high voltage is applied to the capacitor's electrodes.[1] Once suitably charged up to high DC potentials, a thrust at the negative terminal, pushing it away from the positive terminal, is generated.[2] The effect was named by inventor Thomas Townsend Brown who claimed that he did a series of experiments with professor of astronomy Paul Alfred Biefeld, a former teacher of Brown whom Brown claimed was his mentor and co-experimenter at Denison University in Ohio.[3][4]
The use of an asymmetric capacitor, with the negative electrode being larger than the positive electrode, allowed for more thrust to be produced in the direction from the low-flux to the high-flux region compared to a conventional capacitor.[2] These asymmetric capacitors became known as Asymmetrical Capacitor Thrusters (ACT).[5] The Biefeld–Brown effect can be observed in ionocrafts and lifters, which utilize the effect to produce thrust in the air without requiring any combustion or moving parts.[1]
In his 1960 patent titled "Electrokinetic Apparatus," Brown refers to electrokinesis to describe the Biefeld–Brown effect, linking the phenomenon to the field of electrohydrodynamics (EHD).[1][2] Brown also believed the Biefeld–Brown effect could produce an anti-gravity force, referred to as "electrogravitics" based on it being an electricity/gravity phenomenon.[6][7] However, there is little evidence that supports Brown's claim on the effect's anti-gravity properties.[8]

Spaceships: Hulls and This Metal Asteroid Could Reveal Secrets About Earth’s Core | Countdown to Launch

NASA and Arizona State University plan to send an orbiter to the Psyche asteroid, which is believed to be made mostly out of metal. This mission could be the key to understanding the inside of Earth's core.

Between Mars and Jupiter, you can find Psyche, one of the only asteroids that scientists believe might be made mostly of metal and researchers from NASA and and Arizona State University will be sending an orbiter to the asteroid for the very first time.

Exploring Psyche’s terrain could be our only key to understanding what the inside of Earth’s core could be like.

Visiting asteroids isn’t new to space exploration with Vesta, Ceres, Ryugu, and Bennu being some of the most recent mission destinations.

And asteroids, for the most part, have been all the same; usually rocky, airless drifting through the cosmos as leftover debris from a chaotic beginning.

But Psyche is different.

“We’re pretty sure that it’s largely made of iron-nickel metal. And there are very, very few asteroids out in the asteroid belt that we think are made of metal or largely of metal,” Lindy Elkins-Tanton, Principal Investigator of the NASA Psyche mission, told Seeker

Researchers suspect Psyche is an exposed core of a protoplanet, which is a planet in its early formation stages and it’s most likely that the asteroid lost its rocky exterior during violent collisions in the beginning of our solar system’s evolution...at least, that’s what scientists’ best assumptions are.

And no one really knows what Psyche looks like beyond a speck of light, and so the 2022 Psyche mission will include sending back camera images of the asteroid so we can take a look at what a metallic body like this looks like.

Find out more about this metallic asteroid and how the team of researchers plans to explore its terrain on this episode of Countdown to Launch.

MISSION TO A METAL WORLD: Psyche
https://www.jpl.nasa.gov/missions/psy...
"Because we cannot see or measure Earth's core directly, Psyche offers a unique window into the violent history of collisions and accretion that created terrestrial planets. The mission is led by Arizona State University. NASA's Jet Propulsion Laboratory is responsible for mission management, operations and navigation."

16 Psyche
https://solarsystem.nasa.gov/asteroid...
"Unlike most other asteroids that are rocky or icy bodies, scientists think the M-type (metallic) asteroid 16 Psyche is comprised mostly of metallic iron and nickel similar to Earth’s core. Scientists wonder whether Psyche could be an exposed core of an early planet, maybe as large as Mars, that lost its rocky outer layers due to a number of violent collisions billions of years ago."

Or you could just install a zero point one manoeuvre drive, at a default one thousandth of the volume.


Lightsail 2 Sails On Sunlight At Last

Lightsail 2 was launched in June as part of the STP-2 launch on Falcon Heavy, after a few weeks of checking systems out it deployed its solar sail and began attempting to raise its orbit. Earlier this week the Planetary Society declared success - raising the apogee of the orbit higher, even if the orbit on average got lower due to atmospheric drag.

Spaceships: Engineering and Superconductor material could be cool for quantum cats by NICK FARRELL on 11 OCTOBER 2019

Image

B-Bi2Pd needs no magnetic fields

Researchers from the Johns Hopkins University describe a superconducting material, B-Bi2Pd, that naturally exists in a quantum state without the additional influence of magnetic fields usually needed for such an effect.

The authors write that the low-maintenance, stability of this material makes it a perfect candidate for designing quantum systems.

The research will be published today in the journal Science by physicists from Johns Hopkins University.

The paper's first author, Yufan Li, said in a press release: "We've found that a certain superconducting material contains special properties that could be the building blocks for technology of the future. A ring of B-Bi2Pd already exists in the ideal state and doesn't require any additional modifications to work. This could be a game changer."

What makes this superconducting material special is the unique state it occupies as its ground state, or when no other forces are being exerted on it. While other superconducting materials can be forced to maintain a quantum state using external magnetic fields or energy-sustaining "quantum spin liquid".

The researchers found that this material naturally exists in a quantum superposition, in which current can simultaneously flow clockwise and counter-clockwise in a ring of the material. This discovery is the realisation of a prediction made by physicists in the 80s.

The authors write that this property makes it an ideal candidate for quantum systems. However, that does not mean the technology will get picked up, or that if it does we will remember this story.
