Double the fuel economy for cars - for your cars! ?
get good gas milage ~
Twice as many miles per gallon; - twice as many kilometers per litre!
and safer!
and cheaper!
and a higher performance and top speed ! !
All when the proposed new "airliner cars" allow you to get good gas milage.
The latest version of the new "airliner cars" is shown in the diagrams below.
The latest version of the new "airliner cars"
In order to get good gas milage, the new airliner cars have a retractable tail-cone. That gives zero base drag. Consequently airliner cars need very little power or fuel at high speed, when certain associated changes are also included - perhaps as little as a half of the power or fuel required by conventional cars at a given high speed. The total aerodynamic drag at a given high speed has been reduced to perhaps as little as a half of the value for conventional cars.
The airliner cars also have sidewall boat-tailing. That, together with the tail-cone, give aerodynamics which allow the presence of the dome. In turn that gives internal mobility for the passengers and so allows the rear door to be used for the main entry. Consequently, still in order to get good gas milage, ~
Structure can be put at the lower front sidewalls - in all the space below the new emergency door - giving a proper full strength structure, especially for front impact, instead of the large empty spaces of the front doorways of a conventional car. The perfect load lines allow a much lighter structure, therefore a lighter car, and so an easier acceleration and lower fuel requirement during acceleration.
The low fuel requirement both at steady high speed and for acceleration at any speed means that overall the present new "airliner" approach gives an excellent total fuel economy for cars.
The low weight also allows smaller rear wheels and, therefore, easier streamlining at the rear. In particular, it allows a low loss streamline flow over the tailcone. That contributes to making the tailcone practicable and completes the circle of interdependence amongst the items which have allowed airliner cars to get good gas milage.
We must have better fuel economy for cars for the new millennium. We must get good gas milage, we must obtain a low fuel consumption for cars.
For low fuel consumption for cars, we need low aerodynamic drag, ie a low air resistance. Also, for low fuel consumption for cars - we need low weight.
The main feature giving reduction in the aerodynamic drag in the present proposals is the retractable tail-cone. That eliminates the large part of the aerodynamic drag caused by the blunt base. Then, several substantial design changes are made in order to suit the tail-cone.
The initial weight reduction is obtained by moving the driver's doorway rearwards and replacing the lower region of the doorway and door with integral structure. Again further considerable design change is included - in order to make the arrangement both convenient and productive.
Our proposals for a low fuel consumption for cars hold at all performance levels.
We therefore present ~
These have all the above advantages.
They also have low costs, with high safety.
As a bonus, they appear to have potentially, not merely a much better gas milage, but in fact the best gas milage on the road.
Moreover, potentially, they become, in their total costs, the most economic cars on the road - and at all performance levels.
In addition, to top it all, they become potentially the fastest cars on the road!

A part of the better fuel economy for cars is given by the very low aerodynamic drag ~
The fundamental change is the introduction of a retractable tail-cone, retractable and extendable while the car is moving. The cone has axial symmetry, in order to achieve simplicity in its manufacture and operation. There is then, correspondingly, sidewall "boat-tailing" of the cabin to match the cone, with the cabin roof ideally rising rearwards as argued to suit the boat-tailing. The rising roof accommodates a shallow dome, required for the structural changes outlined below. There are also some further associated changes.
The retractable tail-cone gives zero base drag and makes the new "Airliner Cars" become potentially the fastest cars on the road!
A part of the better fuel economy for cars is given by the very low weight ~
Again a fundamental change is necessary.
An area of fixed structural sidewall is added on each side at the lower front of the cabin. The access to each of the front seats is restored by a more rearwards door that leads under the dome introduced above. The resulting lower stresses in the region of the new structure, during front impact, and the correspondingly greatly reduced distortion and dislocation, allow a fully joined up and fairly closed shell as main structure, using predominantly light and low cost or conventional cost materials. There is partly a reinforced double skin. The shell has very low stresses and low distortion, even during front impact, so giving the low weight with conventional materials. With the reduced fuel and power requirements for high speed the resulting total car also has a total low weight with conventional materials. That allows slim and small rear wheels and suspension. It therefore makes practicable the streamlining at the junction between the car proper and the tail-cone which is introduced above.
The very low weight with conventional materials obtained in the manner described above means that the "Airliner Cars", besides being potentially the fastest cars on the road, are also potentially the most economic cars on the road as regards fuel costs, and, furthermore, potentially the most economic cars on the road as regards total costs!
For the other matters mentioned above ~
The low costs
The low costs are given as above by the low stresses and therefore the low cost of materials, by the small size of the components, such as the engine and wheels and suspension, as well as by the good gas milage and therefore the low cost of fuel.
The high safety
The high safety, also, is given by the low stresses and by the small size of the engine.

Brian Stratford's earlier work included internationally acknowedged classics, analysing the low speed flows that have the maximum possible efficiency. Much more recently, workers have used the results from these and other people's analyses to eliminate shock waves and shock losses - in order to provide the maximum possible efficiency on super-critical high speed aerofoils.
Brian worked for a long period with a well known aero-engine manufacturer.
