Description
Desert Aircraft DA-100L Engine with electronic ignition
The DA 100L
is a computer designed high performance model aircraft engine. The finish of
the machining makes a very strong impression of the overall quality. All
components have been designed by Desert Aircraft without compromise, are
machined by specialist firms exclusively for this engine.
The long
conrod, plus the gudgeon pin being mounted close to the piston crown allows the
high torque to be transferred without undue sidethrust. This reduces wear and
piston drag thereby increasing the performance, so much so the DA 100L has the
power of many other 120cc engines.
Piston,
conrod and crankshaft design were with a computer simulation programme
perfectly balanced and harmonized to each other. The DA 100L gives the lowest
vibration levels in it class over the entire throttle range.
A prominent
feature is the very long front crankcase. The third bearing is placed well
forward directly behind the propeller hub. The very stiff and long crankshaft
housing makes for ease of installing the engine under the cowl.
Each single crankcase is machined out of the full from the high tensile aircraft alloy 7075-T6. Compared to die casting, a very expensive method in time and material. This all has the great advantage of a high standard of precision and perfectly aligned crankshaft bearings as well as a superior strength and stiffness; all requirements of a high performance engine with a very long life. Last thing, the optical effect of the perfectly machined surfaces on the DA 100L makes one reluctant to hide all under the cowl.
