Transport problems are becoming ever more urgent in the world.
Such transport vehicles as airships can contribute considerably into the solution of individual, local and global problems.
Nevertheless, so far any attempts to develop any specific airships models that can attract many clients, have failed. Why is it so? The reason is that, in spite of a hundred years of research, they have not been able to develop a really low-cost, manoeuvrable and easy-to-operate transport airship.
In this connection, many companies are again trying to develop airships that could be highly competitive in the market and be sold in large quantities. They make sensational declarations and develop various programs and projects. All this activities will demand impressive financial and time resources and, in our opinion, will yield no results. It is explained by the fact that all these projects do not implicate any radical improvement of airships characteristics: smaller size, lower production and transportation costs and simpler operation. Still, these activities will certainly go on, as there are no other transport means for transporting bulk cargo or for the solution of other specific transport problems.
So, tens of companies will produce few airship that will not settle any large-scale transport problems. This situation will lead to another business failure for these companies which will be aggravated and speeded up by today’s financial crisis.
It is high time for companies, investors and developers of both state and private programs to understand that the only solution of transport problems is the development of airships of totally new generation lacking serious drawbacks of previous projects. We certainly should not follow old ineffective schemes.
For the last decades, airships are using low-cost and safe helium, advanced materials for shell and frame, modern navigation aids and controls and new improved engines. Still there are no radical improvement of airships characteristics. Why is it so? The matter is that accent is made on the development of various versions of frames and external configurations of airships. All these works are based on classical stationary aerodynamics. It is urgent to understand that the use of stationary aerodynamics considerably impedes the development of airships with totally new fantastic characteristics. That is why there is little hope that in the nearest future aerodynamic characteristics of airships (notably, aerodynamic drag reduction), will be improved, as well as their economical, manoeuvring and other characteristics. It is necessary to apply oscillation aerodynamics in the development of airships. It can radically reduce aerodynamic drag and to develop highly effective thrusters of a new type, etc. In its turn, it will considerably reduce engines capacity, fuel weight and consumption. Such airships will be low-cost, fuel-efficient and manoeuvrable. This new generation of airships can be used for the solution of a wide range of transport problems and hundreds of thousands of such aircraft can be produced.
Why are these
possibilities so far not used? There are several reasons for that:
Oscillation aerodynamics is a rather
new science. Its initial research results are
known only to narrowly focused specialists. Most experts in aerodynamics, as
a rule, are quite ignorant of it and for this reason simply ignore this
branch of knowledge. They are traditionally accustomed to develop airships
on the basis of traditional stationary aerodynamics. And nobody will blame
and dismiss them for that. For the last hundred years there have not been
any impressive improvement of airships characteristics, but no individual
aerodynamic expert will be responsible for wasting tens and hundreds of
millions of dollars.
airship based on oscillation aerodynamics, as well as oscillation
thrusters are complicated oscillation systems. Aircraft engineering
centers, especially those specializing in airship construction, are not
prepared for the development of airships as oscillation systems. It
should be mentioned that it is not the airship frame that will be
oscillating. A special propulsion complex will be operating in an
oscillating mode, and the frame flow-around will have extremely low
oscillation components (modern planes, helicopters and airships are
characterized by much more intensive oscillation components related to frame
flow-around; these oscillations are chaotic and are considered harmful).
companies for many years prefer to spend lot of money on insignificant
improvements, but are not willing to risk and undertake research to develop
a brand new airship with oscillating thrusters.
As a result,
existing airships are not highly profitable transport means and their
production and sales are not too large-scale.

aerodynamics and the development of a propulsion complex of an oscillation

2. Low transport cost, especially of bulky and massive cargo.
3. They can hover in place.
4. The development of
extra-heavy load lifting planes and helicopters is impeded by strength

airships and the development of aircraft with 1 000 t working load is
quite feasible. 5. Long nonstop range. .
6. Higher reliability and safety in comparison to planes and helicopters.
7. Airships do not need air-strips (but mooring masts are necessary). Moreover, they do not need to land at all and can simply hover over the ground (however, it is possible only in still air conditions).
Airships with flappingwings.
Airships with flying wings as thrusters have the longest history. Their
production has now been expanded. Still, only few such airships are
produced. Moreover, they are small-sized and so far have been considered
rather exotic. In fact, their flight characteristics are far from being
perfect. These small-sized airships have been before and are now a sort of
funny toys. In their production, oscillation aerodynamics principles have
not been taken into account and they have never been developed as a single
oscillation system. That is why they will never bring forth a breakthrough
in airships engineering.
Still W.Schmidt believed that these funny toys of small-sized airships
are first signs of a revolution in airships engineering. It seems that

AirJelly's environment is the air. Unlike AquaJelly, the remote-controlled
jellyfish AirJelly does not swim through water, but instead glides instead
through a sea of air thanks to its central electric drive unit and an
intelligent, adaptive mechanism. It is able to do so because it consists of a
helium-filled ballonett. The biggest draws at Festo’s Hannover Fair exhibits have been biologically
inspired robotic creatures that show off cutting-edge automation technologies.
Turning once again to nature for inspiration, the company’s engineers this year
came up with robotic jellyfish that either swim or fly. They may look whimsical, but the waterborne AquaJelly and airborne AirJelly make
use of mechatronic design practices, control strategies and actuation methods
that could have serious engineering implications. According to Markus Fischer,
Festo’s head of corporate design, these robots have a degree of autonomy and
adaptive behavior that “will be very useful in the factory of the future.” Both the AquaJelly and AirJelly share a basic construction that consists of a
sphere-shaped body with eight electrically driven tentacles for propulsion. Both
run off rechargeable lithium-ion batteries and are powered by 3V coreless
motors. Given the differing mediums in which they travel, the two robots do have
different bodies — a laser-sintered pressure vessel for the AquaJelly and a
helium balloon measuring 1.35m across for the AirJelly. Festo AG & Co. KG
Fin Ray Effect Recent studies on the functional morphology of fins of
fishes show a surprising biomechanical effect of the fin rays. The
bionic implementations of these constructions led to shape-adaptive wing
profiles and flow control devices. The functional principle has been
patented and is marketed as "Fin Ray Effect" in a line of products
currently being developed. Besides adaptive seat constructions, novel
safe and form-locking grips are of particular interest. Creative
applications in household technology, automation technology, keyhole
surgery, and bionic robotics are in preparation.

1. The existing
transport means - automobile, railway, sea transport, planes, helicopters and
air-cushion vehicles – have a whole range of serious drawbacks:
- these transport
means, the construction and maintenance of highways and railway roads, airfields
and sea ports are extremely expensive;
- high fuel consumption;
- these transport means are environmentally harmful – technical installations
occupy too much land, forests, etc.; oil spills occur, etc. ;
- with some minor exceptions, these transport means do not guarantee
transitional delivery from the producer to the customer (there are a lot of
cargo transfers and stocking);
- transportation of bulky and heavy cargo is impossible;
- high transport costs;
- there is no possibility to set up remotely operated transport (unmanned);
- further expansion in the number of traditional transport means leads to global
transport crisis (highways in large cities are already overtrafficked) .
2. It is
vital to develop new transport means lacking at least part of disadvantages
3. Airships can be
such transport means, as they have the following advantages:
costs are considerably lower in comparison with the existing transport means;
- there is no need of highways;
- they can deliver goods directly from the producer to the customer without any
- ecological safety. 4. Still,
so far airships have not become a mass transport means. There
- low speed;
- special mooring installations and large hangars are needed;
- low manoeuvrability;
- intense lateral wind effect;
- large size and weight. 5. For
several decades attempts have been to make airships a mass transport means.
All these attempts
have failed because of the drawbacks listed in 4. They have tried to solve the
problem through the use of other airships forms instead of cigar-like: cetaecean,
airship-plane, wing-formeds, airships with oscillating
The most promising is a wing- formed airship, Its advantages are as follows:
- smaller size and weight;
- lower lateral wind effect;
- there is no need of special mooring installations (still, a short airstrip is
Airships with oscillating wing thrusters are not highly developed and the
companies do not consider them promising.
6. The existing
airships projects will not remove their disadvantages in any radical way.
Without any doubt,
the today’s boom will yield no results and only few airships will be produced.
7. It should be
mentioned that only wing-formed airships using the wave flow effect
(eradicating aerodynamic drag of the aircraft) can successfully enter the
They will have the
following vital advantages:
- they are tenfold energy efficient in comparison with traditional transport
means (and even with common airships);
- there is no need of mooring facilities and airstrips;
- extremely manoeuvrable, including while hovering and taking off;
- they are immune to side wind;
- a wide range of sizes – from mini-size to 1000 t lifting capacity;
- they can be used for the setting-up of both local and global remotely-operated
transport networks. 8.
Considering the extreme urgency of the development of airships using the wave
flow effect, it is vital to take the following steps:
- to initiate
scientific research and experimental development works;
- to develop a remotely operated airship with 1-2 kg flight weight (task:
tests, demonstration of a new type airship possibilities, serial production of
airships for the monitoring of oil and gas fields, oil and gas pipe-lines,
power supply lines, etc.);
- to develop and 1, 10, 100 1nd 1 000 t airships and to launch their serial
- to set up companies developing and producing airships of various sizes;
- to set up companies specialized in cargo and passengers transporting with the
use of airships.
An airship with a thruster complex of an oscillating type will have the following aerodynamic advantages in comparison with the existing models of airships:
1. The value of thrust (and, consequently, efficiency factor) will be higher in comparison with propellers.
2. Manifold reduction of aerodynamic drag of the airship shell for airships with wings or of a similar form.
3. Higher lift in comparison with airships with propeller engines.
4. Oscillating-type thrusters will perform functions of thrusters, rudders and generators of wave flow-around for airships shells.
5. The improvement of landing, take-off and manoeuvring capability, especially for low speed, as well of on-the-spot manoeuvrability.
Moreover, it is possible to extract energy for engine form heat and potential energy of atmosphere pressure (for this purpose, a special program has been developed).
Airships of this type will have the following advantages:
-a lower capacity engine; -a lower weight of an engine;
-low fuel consumption; -lower weight with the same payload weight;
-better manoeuvrability; -smaller size with the same payload;
-no mooring facilities; -parking without hangars; -lower cost;
-lower cost of payload delivery; -a flying airship with an oscillating thruster looks by far more aesthetic than a airship with propellers.
On the basis of many scientists’ research and our own findings, we have the following knowledge and proof:
8. Our research of an oscillating thruster
There exist non-linear modes of the wing oscillations, when swept area is much bigger in comparison with stationary oscillation modes. This effect can produce considerably higher thrust.
At the oscillating wing thruster, optimum modes can be easily changed at varying flight speed.
A propeller thruster is characterized by non-optimum angles of attack at varying flight speed. Even propeller thrusters only partially solve this problem. With an oscillating wing, it is easy to adjust optimal angles of attack and oscillation law by means of remote control. This will result in higher thrust and thruster efficiency.
8.3. An oscillating wing thruster will simultaneously perform the functions of a thruster, rudders and the generator of wave flow of the airship shell.
At the existing airships, this function is performed by common rudders. In our project, oscillating wings of a thruster will be used as rudders. The effect will be most impressive:
It will be possible to effectively control such airships at low speed, including manoeuvring in place, on takeoff and descent.
There is no need of special rudders.
8.4. Production simplicity and low cost in comparison with propellers
The thruster wing is extremely simple to produce (a symmetrical profile with the same cord along the full span).
