Germany Federal parliamentary republic in central-western Europe

Germany, officially the Federal Republic of Germany, is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, and the Alps to the south. It borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, France to the southwest, and Luxembourg, Belgium and the Netherlands to the west.

Aircraft engine Engine designed for use in powered aircraft

An aircraft engine is a component of the propulsion system for an aircraft that generates mechanical power. Aircraft engines are almost always either lightweight piston engines or gas turbines, except for small multicopter UAVs which are almost always electric aircraft.

Berlin Capital of Germany

Berlin is the capital and largest city of Germany by both area and population. Its 3,748,148 (2018) inhabitants make it the second most populous city proper of the European Union after London. The city is one of Germany's 16 federal states. It is surrounded by the state of Brandenburg, and contiguous with its capital, Potsdam. The two cities are at the center of the Berlin-Brandenburg capital region, which is, with about six million inhabitants and an area of more than 30,000 km², Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions.

Design and development

Introduced in 2015, the LSA850 series is based upon the Weber Motor MPE 850. [2]

The LSA850 is a twin-cylinder four-stroke two-stroke, in-line, 850 cc (51.9 cu in) displacement, liquid-cooled, gasoline engine design, with a helical gear mechanical gearbox reduction drive with a reduction ratio of 3.33:1. It employs electronic ignition and has a compression ratio of 9:1. [1]

Inline engine (aeronautics) Reciprocating engine arranged with cylinders in banks aligned with the crankshaft

In aviation, an inline engine is a reciprocating engine with banks of cylinders, one behind another, rather than rows of cylinders, with each bank having any number of cylinders, but rarely more than six.

Reduction drive Device, containing a different gears.

A reduction drive is a mechanical device to shift rotational speed. A planetary reduction drive is a small scale version using ball bearings in an epicyclic arrangement instead of toothed gears.

Compression ratio the ratio of the volume of a combustion chamber from its largest capacity to its smallest capacity

The static compression ratio,, of an internal combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its largest capacity to its smallest capacity. It is a fundamental specification for many common combustion engines.

Variants

LSA850-105
Model with a power output of 105 hp (78 kW) at 7250 rpm [1]
LSA850-130
Model with a power output of 130 hp (97 kW) at 7500 rpm [1]

General characteristics

Components

  • Fuel type: gasoline
  • Cooling system: liquid
  • Reduction gear: helical gear mechanical gearbox
Propeller speed reduction unit

A propeller speed reduction unit is a gearbox or a belt and pulley device used to reduce the output revolutions per minute (rpm) from the higher input rpm of the powerplant. This allows the use of small displacement internal combustion automotive engines to turn aircraft propellers within an efficient speed range.

Performance

  • Power output: 130 hp (97 kW)
