Durban Company Debuts "Lightweight, Low-Emission, Multi-Fuel
Light Aircraft Engine"
ADEPT Airmotive is showing off what they call 'the world's first
modern GA engine that runs on a range of fuels.' In addition to
normal unleaded petrol (MOGAS), with an octane rating as low as 85,
or standard aviation fuel (AVGAS), the ADEPT 320T engine can
operate on more environmentally friendly alternatives like bio fuel
or liquid petroleum gas (LPG).
The liquid-cooled engine, with advanced electronic engine
management was rolled out last week at Virginia Airport, Durban,
where it powered a South African designed, all-composite SA Ravin
500 light aircraft, which in turn was fitted with a 'glass cockpit'
digital avionics suite from MGL Avionics.
The engine, which produces 320 horsepower, sets new standards
for performance and low life-cycle costs, according to Adept, which
also claims the powerplant 'boasts the lowest lead, nitrous oxide
(NOx) and carbon dioxide (CO2) emissions and noise levels, which
sets it apart from existing technology and benchmarks new standards
in the GA industry. '
At an installed weight of 158 kilograms, the engine is
reportedly 30% lighter than traditional piston engines of
comparable horsepower and offers fuel efficiencies of up to 30%
better than conventional GA powerplants.
"Our technology benchmarks South Africa against the finest
aviation engineering in the world," says Andre Schoeman, Chairman
of ADEPT. The architecture of the 320T's compact engine is entirely
different from that of traditional general aviation engines. It is
a 120-degree V6 engine, which is dimensionally short, ensuring high
levels of strength, durability and smoothness. As a result, it is
well balanced, reducing vibration and materials fatigue. In
addition, the 320T drives its constant speed propeller through a
speed reduction unit, which allows the engine to rev higher,
increasing both engine efficiency and providing optimum propeller
ADEPT used a Digital Prototyping design process that enabled it
to use digital design data contained in 3D models from concept to
final component. A full suite of hard tooling now exists for
commercial production. The emission free foundry process used in
the production of engine castings is the first in South Africa, and
has only recently been introduced by a major European automobile
manufacturer. The process is the result of a technology
collaboration between ADEPT and the German company Ashland
Sud-Chemie. ADEPT further contains its carbon footprint with the
use of recyclable materials in its manufacturing process.
ADEPT was established seven years ago by Richard Schulz, Geoff
Cronje and Raymond Bakker, with initial funding for the project
from private investment company Tanglewood Private Equity (owned by
company chairman Andre Schoeman). Since 2005, UK based
AgustaWestland Helicopters has provided significant support and
continues to fund ADEPT's certification process through the
European Aviation and Safety Agency (EASA).
In 2007, the Department of Science and Technology's (DST)
Innovation Fund invested R10.5m to fund the company to a
pre-production stage. ADEPT is now in discussion with DST's
Technology Innovation Agency and Trade and Investment KZN for
funding to ramp up to full production.
"Through investment in local research and development, it is
fair to say that ADEPT is providing the catalyst for a genuinely
world class general aviation manufacturing industry," says
