We consider $3$-$(\alpha, \delta)$-Sasaki manifolds, generalizing the classic 3-Sasaki case. We show
how these are closely related to various types of quaternionic Kähler orbifolds via connections
with skew-torsion and a canonical submersion. Making use of this relation we discuss curvature operators and show that in dimension 7 many such manifolds have strongly positive curvature. Joint work with Giulia Dileo (Bari) and Leander Stecker (Hamburg).
