Abstract
A divergent slave petal for sealing in variable geometry exhaust nozzles for gas turbine propulsion units includes a base plate for bearing axial forces but having minimum capacity for transmitting torsional forces and a plurality of discrete transverse elements for transmitting transverse and shear forces but not those torsion forces acting about the longitudinal axis of the petal. The base plate and discrete transverse elements are linked by guide elements running along the longitudinal edges of the base plate and by intermediate discrete transverse element fasteners.
