Ship Design Philosophy

Spaceships: Engineering

1. Too bad you can't get anywhere with a propeller in space.

2. Separate drives rotating create super cavitation?

Spacecraft: Engineering and Internal Gravitics

1. An equally important use for these basic grav plates is inertial compensation; by having three sets of grav plates arranged orthogonally, it is possible to combine their pulls in any direction within their area of operation.

2. If a vehicle equipped with such a setup is aware it will suffer an acceleration, the compensators can create an equal and opposite acceleration inside it, ‘cancelling’ its apparent effects for those aboard.

3. If it's not either/or, is the capability already inbuilt, or do you need to spend more money to get it?

4. Obviously, you'd use it for reactionary rockets, since the rockets themselves don't have a gravitational counterbalance.

5. Though, if you think about it, the gravitational counterbalance can't compensate for outside forces gravitationally unbalancing the hull, either.

6.

7. And yet, this doesn't seem hinted at in High Guard.

8. Commercially speaking, if it's cheaper than having an inertial compensation field located in the manoeuvre drive, a lot of free traders would have opted for this.

9. Since the vast majority don't seem to bother to have more than thrust factor/two.

Spacecraft: Engineering and Internal Gravitics

A. Certain manoeuvre drives and lifters link into oversized grav plates designed to accelerate every atom of the ship and its contents equally to reduce or eliminate felt acceleration.

B. That's a part of physics I'm somewhat unfamiliar with.

C. Does that mean, that lifters can create inertial compensation fields, as well?

D. However, the usual approach is to accelerate the hull, lifter, or drive unit rigidly connected to the hull. This brings along its contents, similar to reaction drives.

E. Jumping up and down in a moving truck.

F. I have the feeling that while there is a Consolidated Theory of Gravity, there doesn't seemed to be a consolidated theory of how this is supposed to work.

 

[Arkathan]

From what I can see, lifters... Lift. All of their focus is on opposing the direction of gravity. They are not at all useful outside of a strong gravity field, and they are not good at making whatever they lift move laterally. At least not quickly, relatively speaking.
They make good high tech pallet-jacks, because they generally will not run away from the operator.
Unless you get on a hill. And it gets away from you.
Then whoever or whatever is at the bottom of the hill and in its path is screwed.

 

[Condottiere]

Low level levitation isn't controversial, and apparently, the spacecraft version is basically distributed thrust.

For all intents and purposes, helicopter.

So pushing cargo around doesn't seem too hard, a trained operator probably could manipulate the thrust so that it moves in the required direction.

The question of the strength of a gravity field might not be relevant, beyond how ever far you calculate that force and diameter(s).

 

[Arkathan]

A helicopter can go pretty fast by tilting its thrust. A lifter is more limited than that.
Think normal ground car speeds for lateral shifts if you push it.

 

[Condottiere]

The helicopter comparison is for actual spacecraft lifters.

At the container or pallet scale, walking speed onwards, because vehicle scale is based on weight, as opposed to spacecraft volume.

Spacecraft: Engineering and Internal Gravitics

G. Grav plates, however, cannot change their fields arbitrarily without specialised modifications and therefore are ill suited for dealing with sudden or violent accelerations.

H. Grav plates take a few seconds to ‘warm up to speed’ when turned on or changing intensity, so collisions, scrapes, weapon impacts and other such surprises are all things the inertial dampers are too ponderous to adequately deal with, whereas planned accelerations are easily handled.

I. Latency, what fun.

J. You fly across the room, but halfway, drop down.

K. Since when inertial compensation catches up, it robs you of momentum.

Spacecraft: Hulls and This Should Be Impossible...

My name is Alec Steele. I am a blacksmith, amateur machinist and all-round maker of all-things metal. We make videos about making interesting things, learning about craft and appreciating the joy of creativity. Great to have you here following along!

I guess titanium steel does exist.

But doesn't seem to be a good idea.

Who came up with this concept?

Spacecraft: Electronics, and Sensitive Probing

1. Now that I think of it, I don't think I've ever seen a comprehensive, and sensible, sensor table.

2. I tend to think size, movement, and noise, would be the primary means to detect an object in space.

3. I guess borrowing targetting modifiers would be the initial step.

4. Short range would add a plus one, long minuses off two, very minuses off four, and distant minuses off six.

5. Every full kilotonne of the target, you add one.

6. Which caps at plus six, for six kilotonnes.

7. Rapid change in position would depend on how long an area of space has been under observation.

8. You note that by that rapid movement in space, a detected object attracts attention.

9. Or, by rapid movement, it becomes detectable.

It's not bad; I think it avoids any egregious overuse of obvious tropes.

Spacecraft: Armaments and Gauss Cannons

I was inspecting the weapon systems for a substitute for the man portable fusion guns for the TRI Fighters.

Then it occurred to me, how fast are groundscaled gauss slugs, actually?

Because, if they're too slow, they might slam into the spacecraft that they originated from, considering manoeuvre drive factor/one acceleration is nine and four fifths metres per second squared.

Railguns are supposedly close to light speed, but it isn't specified for mass drivers.

Spacecraft: Passengers and 9 NEW Things that HAD to Be BANNED on Cruises

Before you go on a cruise, it's important to know which items you can & cannot bring on a cruise. With recent changes by popular cruise lines, These are the latest items to be banned on cruises - some of these are so unexpected!

All cruise line have guidelines & rules - a prohibited items list. In recent cruise news, we've seen Carnival, Royal Caribbean & other cruise lines update the things that are banned on cruise ships.

From cabin door decorations you might have thought of bring to cruise hacks you may have thought of trying, you need to be aware before you go on your cruise vacation.

1. Shipboard electrical systems interference.

2. Disturbing other passengers (and crew).

3. Communications devices.

4. Illegal substances.

5. Sniffer dogs.

6. Military uniforms.

7. Door decorations.

8. Interference with cabin layout.

9. Heating elements, like cookers and travel irons.

You neglected to mention the sponsor's message at the start...

I thought that would be an Easter Egg.

Depending on your point of view, premature or overdue.

Spacecraft: Cargo, Shipping Space and Ground Vehicles

1. What's the volume of a Mini Cooper?

2. Convertible: L x W x H: 3863 x 1727 x 1415 mm

3. And if we leave the top down, less.

4.

5. Let's say two metres, by two metres, by one metre.

6. That would be four cubic metres.

7. Maybe, even three and a half cubic metres.

8. Equivalent to a spacecraft volume of a quarter tonne.

9. Which, if clamped externally to the spacecraft hull, is how much the engines' load would increase.
