Vehicle Construction Kit Supplement 3: Revolutionary Vehicles

Suggested Price $2.53

This is supplemental material for the Vehicle Construction Kit /product/225337/

Revolutionary Vehicles adds new components and options for your VCK designs, inspired by the renaissance, industrial and early modern eras.

  • Internal combustion engines
  • Manufactories
  • Refineries
  • Rockets
  • Batteries
  • Wind power and water power
  • An overhaul of the VCK steam engine component
  • New options for quarters components, including early forms of computers.
  • Rules for giving vehicles aerodynamic or hydrodynamic streamlining; for granting a bonus to speed due to a vehicle's size; and for calculating a flying vehicle's rate of climb
Example constructions include:
  • Ship mill
  • Eight-sailed windmill
  • Runabout, an early automobile
  • Steam aircraft
  • Coastal class airship
  • Continental class airship
  • Cutter, a fast cargo sailing ship.
  • Light observation helicopter

Also, back when you showed me a rough idea of how to convert cannons to modern guns, I forgot to ask how crew requirement was affected.

The base crew requirement remains the same, however from Early Modern onwards an artillery component can have autoloaders. This increases the cost by one-third, but decreases the crew requirement by one-third. Autoloaders do not require Power Points (they use auxiliary power included in the component).

(This is my rough estimate based on tank guns. I haven't reality-checked this against modern naval cannons yet).

How the hell would you make a helicopter? The PP requirement for Rotors just to generate the required lift is INSANE.

I'll double-check my calculations.

The values are correct :) . Okay, here's a full explanation!

What we think of as a modern helicopter is powered by gas turbines, a component I haven't introduced yet (as I am saving it for a "modern" supplement - Revolutionary Vehicles stops at piston engines). A single aviation gas engine component produces 15 PP to 30 PP. An apache gunship for example has has 2 modern rotors and 3 gas engine components.

Early modern helicopters using piston engines require much larger engines. For example, the 1940's Vought-Sikorsky VS-300 (weighing about 1,200 lbs) uses an aero piston engine, the Franklin O-200 (about 300 lb). This is 5 components-worth of engine: at 7 PP per component, this is 35 PP. With an early modern rotor, this gives a speed of 60 mph and a Lift of 4 (pleasingly close to the real helicopter).

I included modern rotors in the base book, because it can represent a magical creation. Elemental engines give 12 PP per component, so a couple of those gives a decent...See more

I'll also add for low-lift rotor systems (particularly the industrial variant) the intent is that you are combining it with other forms of lift, such as magical lift, or even fixed wing combinations are possible.

I noticed that flight speed has several multipliers for different factors. Do you multiply the flight speed by each multiplier, or add the multipliers together then apply it to flight speed. For example the Streamlining Levels and Size Bonus on the Propellers.

You multiply by each multiplier. For example, the Continental-Class Airship on page 17 has a base speed of 63 mph (early modern propellers with 2 Power Points). The multipliers are x0.4 (drag from gasbags), x2 (size), and x1.25 (good streamlining). Applying each multiplier in turn (63 x 0.4 x 2 x 1.25) gives you the final maximum speed (coincidentally 63 mph).

Rules Edition(s)
Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
