My model of coanda effect flight sauser. The first successful test.
My video of my prototype vertical take-off and landing unmanned aircraft,
which uses the Coanda effect to generate lift by blowing air from a central
fan over its curved surface. It is a model of Aesir craft..

Just for information, Coanda effect is : "The Coandă effect /ˈkwɑːndə/
is the tendency of a fluid jet to be attracted to a nearby surface."
Homebuilt DIY Flying Saucer (Economy Model) Concept

That Moller skycar scares me. Have you seen the video? I can make one
that's safer and quieter, if not faster, at one tenth the cost. Ok, at least
I think so. This is just a concept sketch, but now you can test drive it,
thanks to blender's game engine. Our economy model experimental electric
powered parachute supports vertical take-off and landing and has built-in
collision reducing air bags, parachute, solar, fuel cells. Inflatable,
collapsible construction for easy storage and repair.
For entertainment purposes only. This "unit" has not been tested and I may
have accidentally booby trapped it with the dimensions I have, so if you
build it, you are on your own. The bottom fan could just as easily be a
Tesla Turbine, but unlike Tesla's craft, this one does not need to run on
transmitted power. We have on-board power now, thanks to modern
advancements in lithium ion batteries and fuel cells. Again, this is just
an economy model terrestrial craft. If you want cheap space travel, you're
asking for a piece of the sky. That would be like asking for fluoride-free
tap water, but it's your money...
A flying ship using the Coanda effect to generate horizontal power
A flying ship using the Coanda effect to generate horizontal power and
comprises a brushless direct-current motor , a propeller, a steering engine
, a battery, a guide vane group containing guide vanes and a ducted body.
The propeller is fixed on the brushless direct-current motor. The flying
device is characterized by further comprising a fixing block, wherein the
brushless direct-current motor is connected with the upper surface of the
fixing block. One ends of the guide vanes are connected with the fixing
block, the other ends of the guide vanes are connected with the inner
surface of the ducted body, and the battery is fixed on the lower surface
of the fixing block. The flying device further comprises a direction
control steer and a control steer connection frame, wherein the direction
control steer is formed by bending a rectangular plate along the direction
two parallel edges into an arc shape, and the control steer connection
frame is fixed on the ducted body and used for supporting the direction
control steer. The flying device is stable in flying, easy to operate and
stable in suspension in the air.
The invention provides an electric leveling support system, comprising an
electric leveling leg, a leveling control box, a relay box and an
inclination sensor. In the system, an electric control system is adopted
and a lead screw is driven to rotate via a speed reducer by a
direct-current motor so as to stretch or contract the leveling leg, so that
many problems of a hydraulic system at the aspects of installation, use and
maintenance are solved; not any oil leaks, no extra weight is increased
because of hydraulic oil, and even no valid use space is wasted for storing
the hydraulic oil; the weight of the electric leveling support system is
far lighter than that of the hydraulic system; and therefore, the fuel
economy of a remodeled car can be ensured.
A propelling device and a ship having the same are provided to jet water
through an annular nozzle generating Coanda effect after accelerating by
pumping and inflow of the water. A propelling device comprises a water
intake duct, a pumping unit, and a jetting unit. The water intake duct
guides the movement of seawater flowing into through a seawater inlet. The
pumping unit pumps the seawater to flow into through the seawater intake
duct. The jetting unit comprises an annular nozzle having Coanda inner
walls and annular outer walls. In case of discharging the seawater through
an outlet between the Coanda inner walls and the annular outer walls, the
jetting unit generates Coanda effects in the coanda inner walls to jet the

VZ-9 AV Avrocar (VTOL)
The Avro Canada VZ-9 Avrocar was a VTOL aircraft developed by Avro Aircraft
Ltd. (Canada) as part of a secret U.S. military project carried out in the
early years of the Cold War. The Avrocar intended to exploit the Coandă
effect to provide lift and thrust from a single "turborotor" blowing Exhaust out the rim of the disk-shaped aircraft
to provide anticipated VTOL-like performance. In the air, it would have
resembled a flying saucer. Two prototypes were built as "proof-of-concept"
test vehicles for a more advanced USAF fighter and also for a U.S. Army
tactical combat aircraft requirement. In flight testing, the Avrocar proved
to have unresolved thrust and stability problems that limited it to a
degraded, low-performance flight envelope; subsequently, the project was
cancelled in September 1961.
