Fresh Breeze:BulliX

Cosmos

The Cosmos 300 from Vittorazi promises a lot of power with a low power-to-weight ratio. Therefore, this design-wise sophisticated engine is mainly suitable for trike operation. The engine concept is based on a liquid cooling system, which optimally dissipates the heat from the combustion chamber: This compact engine effortlessly masters long climb phases.

Airbox

The airbox integrates elegantly into the design of the Cosmos. The air flow was chosen in such a way that the ideal air pressure is permanently present at the carburetor: the result is constant performance development.

E-Starter

An electric starter for the Cosmos is available as an option. Of course, the electric starter version is also supplied with a manual starter - should your battery become too weak.

Exhaust

The exhaust on the Cosmos is a real eye-catcher. The two-part exhaust chamber contains a complex inner workings, which causes an even performance development.

Gearbox

The spur gear transfers the engine power to the propeller hub. The gear reduction of 1/3.04 is specially chosen for large propeller diameters. A balancer shaft ensures less vibration during operation, which also promises a longer service life of the engine from a mechanical point of view.

Carburetor

The Tillotson membrane carburetor guarantees trouble-free operation in every flight position with simultaneous maximum performance in terms of performance and consumption. The ingenious 2-membrane system also eliminates the need for a mechanical ball pump.

1,60m propeller

The engine is designed for trike operation and comes with a 160 cm propeller from Helix-Carbon. This propeller is specially designed for the gearbox of the Cosmos300, which means that there is no need to change the reduction ratio.

Powerline

The Cosmos 160 cm is specially designed for trike operation and therefore comes as a complete unit including a motor frame and propeller cage. The pilot benefits from this overall package, as redundant parts are eliminated. All single-seater trikes and the CrossX can be equipped with this engine unit.

Vittorazi

This ultra-modern two-stroke engine is characterized by its low power-to-weight ratio. The powerful engine can also be relied on in continuous operation. The well-thought-out design relies on a liquid cooling system, which guarantees optimal heat dissipation from the combustion chamber. Especially during cruise flying, this engine impresses with its quiet engine running.

1,25m propeller

The 1.25 m propeller from Helix Carbon, perfectly matched to the engine, is made of unbreakable, carbon fiber and meets the highest safety standards. Compared to other propeller manufacturers, the Helix Carbon propellers are particularly characterized by their smooth running and the much more efficient blade profile.

Airbox

The airbox is available on all Polini engines. It filters the air and dampens the intake noise extremely effectively.

Exhaust with Helmholtz

Typically for Polini engines, the resonance exhaust is specially designed for flight operations. A Helmholtz resonator developed by Fresh Breeze ensures even more performance. The exhaust is multi-part and connected by break-proof springs to decouple the vibrations from the exhaust. The shapely muffler reduces engine noise to a minimum.

Transmission

Due to its design, the fully enclosed gearbox is low-maintenance and almost wear-free. The reduction ratio of 2.8: 1 is designed so that the maximum engine efficiency is developed at 8000 rpm. The centrifugal clutch is integrated in the gearbox.

Cooler

The streamlined cooler supports the liquid cooling system in its work and guarantees thermal stability. This means that the engine temperature is optimal even for long climbing phases.

Fuel pump

A small, light fuel pump supplies the carburetor with fuel. The pump does not need any electricity at all because it takes advantage of the changing pressure conditions in the crankcase. This small feature enables the use of deep-lying tanks, which has a positive effect on the center of gravity of our aircraft.

Engine unit

In this configuration, the engine is designed for the "Pro SportiX" system. The entire periphery of the engine is taken up by the engine frame.

Electronics

A generator with a power of 80 W at 5500 rpm is installed in the engine and is supported by a battery. This electrical system enables advantages such as electrical starters, electricity for radio etc.

Carburetor

The slide carburetor prepares the mixture for optimal combustion. This carburetor concept entails a linear increase in power. With this carburetor, the pilot has very sensitive control over the engine.

This highly efficient 4-stroke engine -made in Switzerland- works according to the DOHC principle (double overhead camshaft). Equipped with a fully electronic control, this engine is particularly economical, but it is one of the most powerful engines from our company for the <120 kg class. The altitude compensation is one of the highlights that distinguish this motor.

1,40m propeller

The 3-blade propeller from Helix Carbon ensures even power release.

The interlocking blade roots together form the hub of the propeller and are fixed in place using a propeller pressure plate.

Exhaust

The multi-part exhaust made of rustproof stainless steel is swinging / uncoupled throughout. Due to the light and shapely rear silencer, this easily passes the noise test of the DULV with just 55 dbA.

Electrical

The engine naturally also has a generator that is responsible for the voltage supply to the instruments and for charging the battery. The built-in battery ensures a trouble-free engine start.

Cooling

The liquid-cooled engine is extremely stable thermally. The already efficient 4-stroke engine has an optimally positioned water cooler. The water pump is driven directly via the balance shaft. This efficient design is part of the lightweight design concept of this engine.

Transmission

The engine, which originates from racing, was modified at Fresh Breeze for flight use. The belt transmission integrated in the motor frame is adapted to the respective propeller size. The wide strap can be tensioned by means of an eccentric. The centrifugal clutch is on the crankshaft side - this safety aspect has not been left out of this premium product.

Motor control

The holistic engine control influences mixture preparation and ignition in this engine. With the help of the sensor data - pressure, speed, temperature - the engine is able to guarantee optimal combustion in all operating conditions.

Propeller cage

The two-part double ring cage made of high-strength aircraft aluminum is quick and easy to assemble and comes in two different colors. The line deflectors between the cage and trike support the function. When starting, the lines can easily be placed in the line holders.
