I’ve searched for evidence that this already exists, but found none. Today’s invention is a part of gun control logic for military tanks.
When a tank commander selects a target, probably on a touch screen, the system calculates the fastest route to bringing the main gun around to a firing position.
There are three main components to be considered.
1) What is the current rotation rate and direction of the body of the tank?
2) What are these values for the turret relative to the main body?
3) what are the linear speed and direction of the tank body?
Using these values, the system may choose to send power to the sprocket wheels and/or to the turret drive motion. The system works out whether it’s faster to go anti-clockwise or clockwise and selects the various motor settings accordingly.
Since it also understands inertia, the computer dedicated to this modelling task will take account of the need to slow the barrel’s rotational and translational speed, at the end of its movement, so that its time-to-target is minimised.
The crew would probably need racing seats with extra padding, to cope with the sudden changes in speed and direction.
If you ignore the closed-cockpit record breakers on Bonneville flats, motorcycle aerodynamics is a field which has been largely neglected. It’s just hard to do much modelling of a system whose entire geometry is changing every few milliseconds.
There are however some obvious bloopers to avoid. The first of these is the flapping dewlaps of leather which tend to increase drag on riders -even in race-tight, in one-piece suits. Some examples can be seen in slow motion here.
Today’s invention is an improvement to race suit streamlining.
Just before a race, a rider gets on his/her machine. A vacuum pump is attached to a valve in the back of the airtight suit, which evacuates it like a coffee pack. A plug is inserted in the inlet and sealed, so that the armour segments are more effectively attached to the body.
The suit would incorporate small stretch panels to allow a little body movement for weight transference on the corners (and occasional breathing). A cold water bladder would be worn on the inside of the abdomen area of the suit to help reduce body temperature in the absence of ventilation. Thus there would be no spare leather to flap around and slow these heroes down.
How many dog walkers have been injured by their substantial canine deciding to suddenly leap in the direction of some squirrel/small dog/rabbit?
…Dog sees small dog across road and leaps toward it…Hand holding the lead tenses and yanks shoulder joint…Shoulder reflexes snap all the ligaments taught…Nerves get stretched. (You can buy spring inserts but these don’t stop a dog walker being jerked off his/her feet).
It’s happened to me twice, resulting in some reasonably serious damage.
Today’s invention is a safety device designed to prevent injury to both dog walkers and their daft animals.
When an impetuous pet leaps away with a force great enough to tear a plastic restraint (pink), a small charge, as in an automotive airbag, fires backwards as shown. This causes the dog’s chest harness to stop the animal in its tracks, without placing stress on the owner’s arm. The internal cable (blue) maintains the link with the dog (but without snapping taught).
(It might work best if the charge were actually based on compressed air that the user could recharge after each use).
I don’t much like caravans (or camper vans, if you prefer). This is probably because, when driven on twisty UK roads, they tend to attract bad drivers who cling to their back ends and are afraid to overtake the combined length of van+car.
Nonetheless, I am a huge admirer of applied mathematicians. Today’s invention relates these diverse phenomena.
It seems that mathematicians have been trying to find the biggest rigid shape which can pass down a passage with right angle bends in it. A near-perfect solution is shown in pink in the diagram.
Today’s invention is to create caravans which have this shape when viewed from above. This allows them to have the largest possible floor area, whilst also being able to negotiate the right angled corners of one lane of a city road network.
People who drive race cars understand that they are hard to enter and exit. There may be roll cages and carbon fibre tubs to negotiate as well as seat bolsters and head restraints.
Much of this driver packaging doesn’t work very well in a road going sports car. Not only do race cars offer a restricted field of view, but ordinary drivers are a good deal fatter and less mobile than the average track pilot.
Yet, roadgoing sportscars tend to mimic the features of their racing brethren. This means that the ‘racing’ seat option will often have side and leg bolsters which rise high above the seat surface to provide some bracing as you enter the Mulsanne straight (in your dreams).
After a short while, the leather or alcantara gets so badly scuffed here that it looks like an old teddy bear’s paw. This is costly to fix/replace.
Today’s invention is therefore sportscar seats whose bolsters hinge out of the way to allow the driver/ passenger easier access (along axes A-B and B-C) (There would need to be a locking mechanism too).
Yes of course these can be motorised (at the usual enormous cost of options).
