In the 1950's, Terrence Nonweiler produced a design for a delta-
What he'd succeeded in doing was to create a three-
Every aeromodeller will look at a Caret wing and pronounce it unflyable because of its negative dihedral (known as anhedral). They know that positive dihedral (having the wingtip higher than the wing root) aids stability whereas negative dihedral causes an unstable aircraft.
However, there is a little-
Caret wings are remarkably stable at low speeds, even at the high angles of attack required for landing, because if you think about the geometry, the leading edges of the Caret wing are somewhat like the leading edge slats on conventional aircraft; the airflow sees them as drooped. Caret wings can also exploit ground effect: the incoming airflow gets trapped between the runway and the underside cavity which allows the wings to fly at a lower airspeed. This same trick used on the fast passenger carrying catamarans.
Aspirespace and our friends have had tremendous fun over the years flying Caret-
The Caret wing was the first waverider concept, but now we know that the important features are just the sharp wing edges and some degree of underside concavity around those edges.
