Let G/H be a Riemannian homogeneous space. For an orthogonal representation ϕ of H on the Euclidean space R k+ 1, there corresponds the vector bundle E= G× ϕ R k+ 1→ G/H with fiberwise inner product. Provided that ϕ is the direct sum of at most two representations which are either trivial or irreducible, we construct metrics of constant scalar curvature on the unit sphere bundle UE of E. When G/H is the round sphere, we study the number of constant scalar curvature metrics in the conformal classes of these metrics.
