A traditional leaf blower has either an electric motor or
stroke piston engine driving a centrifugal compressor. It
makes more sense to combine both the engine and blower-
unit by using a small turbine engine. Small axial flow
engines are already on the market for just a few
dollars, and can produce large amounts of thrust compared
a typical home leaf blower. If one of these engines was
combined with a collapsable tube and small fuel tank it
would make a great lightweight but powerful blower.
Advantages include much more thrust and lighter weight
huge backpack) meaning less work and risk of injury for
care workers. Jet engines can run multiple types of fuel
including biofuels for eco-friendliness. Additionally, jet
are easier to come by and can be cheaper than the mixed
fuel used by 2 stroke engines. The Jetcat model turbines
thinking of have FADEC control and electric starting, so no
more trying to pull-start a leaf blower that has been sitting
the garage for a year.
Disadvantages are the high cost, extremely loud noise, and
the possibility of hot or hung starts, failure to light off,
flameouts, compressor stalls, and uncontained engine
Before anybody says it, I know that there are turbine
out there, but most of them are very large and designed for
debris or snow removal. This idea is for a small home leaf
blower designed for consumers or lawn care services that
be kept on a shelf.
Optional afterburner available for snow and ice removal at
additional cost and liability.
