Every one welcome to give it a try . But this is a specialist job although easy to build . It is an engineering job for some one, who is aero and hydro dynamic expert and, has the skills and workshop. The model can be build from components of radio control, RC, flying models. Figure 1 is a guide line to the components needed. Each arrow between two components indicates a wired link between both. The link between receiver and RC is wireless.





You need at least two exact similar electric ducted fans, EDF, one electronic speed control, ESC, for each fan, a radio control with receiver, a voltage regulator and a battery. You are not building a flying model, you are building a model for test on the ground. So you may be better off to buy or use a strong vehicle battery rather than buying flying model battery, which is not safe.

In addition to RC components, you need four pieces of light but strong enough pipes or ducts. It is important they are very short. You may just buy one long one and cut it to four pieces. Fit the four pieces to each other like figure 2 at an angle of 45 degrees. There are three inlets marked as 5, 6 and 7 at the front. Inlet 6 is not bigger than cross sectional areas of both fan air passages. Each other two inlets, 5 and 7, is half the size of inlet 6. Fit each ducted fan at the back of pipe 1 and 4 as in figures 3 and 5.




It is very important that the area of inlet 6 is not bigger than the areas of air passages of both ducted fans and the area of each inlets 5 and 7 is not bigger than half the size of inlet 6 area as each is equal to air passages of the fan in the same duct. Not all similar ducted fans have similar sizes. So it is important to measure air passages of each one. Air passages of a fan is the total area gaps between blades.

A fan with five blades, for example, also have five area gaps. Assume figure 4 is a fan of five blades and the dimensional air gap between each two blades is 1, 3 and 5 units as in the figure. Consider the gap as an irregular rectangle So the area of the air gap is (1+3)/2 x 5 = 20 units per air gap. But we have five air gaps. So the total air gap area or air passages area becomes 20 x 5 = 100 units air passage area of the fan..






Drag Controllers

The model you are building is a ground operating model to exploit natural atmospheric pressure to get an extra push without cost. This extra push comes from natural atmospheric pressure, which theoretically is equal to the pressures, which both fans generate. The exploitation of this free push comes from pressure differentiation between natural atmospheric higher pressure point and falling atmospheric lower pressure point of figure 3. This pressure differentiation depends on four factors:

1- The size of air inlets of figure 2 must not be bigger than air passages of the fans. This has been discussed and it is the most important one.
2- Area size between NHAP and FHAP, figure 3 as example.
3- Fan generated drags have to be neutralised. This is also as important as the size of air inlets of figure 2.
4- External drags have to be neutralised. They may not become a serious issue.

When both fans operate, they cause drags, which can neutralise natural atmospheric higher pressure against falling atmospheric lower pressure pressure as shown by doted arrows of figure 3. There are drags moving backward parallel to air streams forced out by the fans. These drags destabilise and lower natural atmospheric higher pressure at the back against falling atmospheric lower pressure at the front. Falling atmospheric pressure at the front also causes drag from natural atmospheric higher pressure point at the back to the front. These drags also destabilise and lower natural atmospheric higher pressure at the back against falling atmospheric lower pressure at the front. To neutralise these fan generated drags, we have to fit fan drag controllers at the front and at the back to both fans as shown in figure 5.

These drag controllers are pipe extensions made up of body and neck as in figure 6. They should completely eliminate fan generated drags when made wide and long enough. They can be made from light items like plastic sheets. But at the front the sheets needs support of some thing like a cage.

The area between natural atmospheric higher pressure and falling atmosphering lower pressure, figure 3 for example, has to cater for the thrust of both fans and atmospheric pressure. Atmospheric pressure on sea is about 1.00kg per one square centimetre. Fan thrusts usually comes in Kilograms. This is something not to worry about because the area in question will be big enough when size concerned. This is the same area of inlet 6 of figure 2. This area is about 55.00cm sq for two fans of around 7.00cm internal diametre.



External drag may become an issue if fast speed becomes something important. But HAAM can be made a very powerful moving machine without fast speed becoming an issue. Uneven body of HAAM can cause negative drag obstructing the speed over certain speeds. These uneven areas can be covered as shown in figure 7. But external drag doesn't become an issue with a prototype model.



How to test The Thrust of Your Model

First test the thrust of each ducted fan before fitting them to the model. When the model is ready test both fans with the model at the same time. The thrust of the model should be at least three times higher than the thrust of one fan or at least one and half times higher than the thrust of both fans. There are many ways to do the test. Please search online to find various ways of it. If you are using vehicle battery, ensure the wire is long enough and has the correct density to take the high current, which could be over 100A.

Can HAAM really generate extra output without input or cost

Yes, HAAM can generate extra output or energy without input or cost apart from the cost of equipment. This is true theoretically and practically when it comes to application. Figures 8 and 9 prove this statement.



Figure 8 above made up of two parallel ducted fans. When they operate, both draw air from the front to the back. This creates two higher pressure points, 1 and 2, at the back. Both pressure points push the fans forward.



Now redesign the ducts, pipes, of the fans like figure 9 above. Now when both fans operate like before, a third higher pressure, higher pressure 3, develops naturally without any input. This third pressure is an atmospheric Pressure differentiation between points HP and LP. It develops because atmospheric pressure at LP point falls because both fans draw air from LP point. This third higher pressure can be made as powerful as the power of both fans put together.

Improving Ducted Fans

The efficiency of a ducted fan can be improved by eliminating the air gap, figure 10, between the tip of the fan blades and duct. This can be done by putting a ring around the tip of blades as in figure 11. The ring has to cover the tip of each blade from the front to the back or from end to end. The ring has to be covered at the front and back as in figure 12. The gap between the ring and, the duct and covers may be sealed with the use of a lubricant. .







Ducted fans of HAAMs can be further improved by enlarging their air passages or reducing their size and weight for the same power. A HAAM needs at least two ducted fans operating in parallel to provide a balanced forward thrust. Both or all ducted fans can be operated with one engine outside the fans by coupling each one to the engine with a driving belt or shaft.
