A motorfloater is
an ultralight airplane with a small motor that flies very
slow. The pilot sits completely out in the open, flying in a
simple and easy way. It's a lot like a paramotor but with the
stability, control, wind tolerance, and crash safety of a light
airplane or airchair. The motorfloater differs from other airplanes in having a very light wing loading, allowing slow flight and tight turns.A motorfloater wing loading is similar to a hang
glider (well under 2 pounds of gross weight per square foot of wing). and they are light (United States FAR Part 103 compliant, less than 255 lbs. empty).My
idea of a motorfloater differs from paramotors, powered hang
gliders, and
microtrikes in having a tail (for pitch stable flight), a fixed rigid
wing (again for stability, without the paramotor issue of canopy
collapse), and more fixed structure around the pilot (for crash
protection).
I use simple controls, garage
technology construction, and a paramotor engine. The stall and spin
characteristics (if any) should be very mild and forgiving, and
the plane should be unable to do an accelerated stall with moderate weight
pilots. The emergency parachute is hand deployed, like a hang glider
system, a realistic option as long as the pilot is completely out in
the open.
Flying in the open air flying is a special kind of experience,
not the same as flying inside a cockpit.
The Bloop is a Pig glider with an engine added. (See the Pig Page for
details on this airchair glider.) The Bloop with engine and
emergency
parachute weighs about 187 pounds. The power package is a modern paramotor
system, aVittorazi
Moster 185
two stroke engine (25 hp.) with a 1.3 meter two bladed propeller. The
engine is started by a rope pull and uses synthetic oil mixed
into the Avgas fuel.
For simplicity, the Bloop has no ailerons, the plane is controlled by
the rudders and elevator only. This is a traditional two axis system
(ala Weedhopper, Flying Flea, Skypup, early Quicksilver MX, etc.) which must be flown using two axis flying
procedures. For example, when you are rolling on the ground in a cross wind, you keep the nose low
so the weight is on the wheels, which will keep the wings level.
I don't taxi much, I walk the plane to and from the runway, which is
practical
with a well balanced airplane that isn't heavy. A
pilot who walks his plane instead of taxing can see better, has better
control, and is
safely out of the plane if dangerous weather suddenly arrives. Walking
the plane reserves your hot engine time for flying instead of ground moving,
and it avoids blowing dust over all over the airport. In consideration of
other traffic, you can scoot onto or off the runway while seated in the aircraft when necessary.
.
Pilots often ask why the Bloop does not use a more conventional landing
gear system, with a tail wheel or nose wheel. My answer is that I have
not seen a conventional nose wheel or tail wheel setup that would allow for
high wind safety at this wing loading.
A motorfloater must be able to roll with the nose low and stop with the
nose down, firmly gripping the ground, so it will not be blown away.
For this reason the nominal start and stop positions are expected
to be nose down on the skid, like trainer sailplanes
or airchair gliders.
Hot
pilots who want speed and thunder will have little interest in the
Bloop. Motorfloaters are for the other kind of flying, The
name
"Bloop" is intended to suggest a kind of combination blimp and
plane, a slow and casual flier. This is a non-commercial project, so
nothing is for sale, but I encourage commercial production of something
like this. All of the materials on my websites are freely available for
whatever purposes the user may desire.
What is the plan ..?
The Bloop prototype is being reworked
into the Bloop2, which I hope will fly slower and have other good
flight and ground roll characteristics. I hope to resume regular motorfloater
flying this spring or summer (2012). A higher lift airfoil is
planned, to get more of the benefits of slow flight, including the
experience of open air flying, comfort, low fuel consumption, crash
safety, and the opportunity to make gross low airspeed mistakes without
severe penalties.
The technical drawings which describe the Bloop as I have flown it are
available for viewing and download at my photo gallery (6 albums, 92
drawings, see menu above).
