ASW 24
- Background information on the
original -
The ASW 24 was
designed by Schleicher's Gerhard Waibel, with Delft University
professor Loek Boermans undertaking the role of aerodynamicist. The
prototype made its first flight in 1987, having entered serial
production later the same year. It nominally remained in production
until 2000, although only a score were built in the mid-to-late
nineties.
It entailed a large development effort, as it was a complete departure
from the preceding ASW 19 and pioneered several successful
innovations. The fuselage, airfoils, wings and empennage were
completely new, as well as many systems, e.g. the electrical ballast
management. The structure employed a large amount of the then still
exotic carbon fibre. The OSTIV Award-winning safety cockpit made use
of an organic shape, tall sidewalls, crumple zones and exotic aramid
fibres for crash protection. A large wheel with a disc brake and a
large canopy with excellent visibility were other strong points of the
type.
The ASW 24 was moderately successful in competitions. It won a single
World Championship in 2001, fourteen years after its market launch. As
the contemporary LS7, the ASW 24 overstretched the technology
available at the time: it has excellent performance in the cruise but
less so in the slow flight range. The higher-than-usual thermalling
speed revealed itself a disadvantage in the typical competition
gaggles, and its performance degrades significantly when subject to
turbulence, rain or wing contamination.
According to World Champion Sarah Steinberg, it needs to be always
proactively flown in thermals, thus imposing a higher workload upon
the pilot. Notwithstanding, the aesthetically pleasing ASW 24 is a
comfortable, safe and pleasant sailplane with high cross-country
performance that remains competitive up to national championship level
in most countries.
The fuselage of the ASW 24 was the basis, with small modifications,
for the subsequent ASW 27, ASW 28 and ASG 29. It was superseded in
production by the ASW 28.
