Blade platforms (26) for compressor blades with airfoils (22) in high solidity relationship have edges of a major portion (44) a minor portion (46), and a canted intermediate portion (48). Minimum clearance (54) exists between the major portions (44) whereby twisting during stackup or operation is avoided. A circumferential seal (60, 64) is located under the platform coincident with major portion (44).

A bladed drum type compressor assembly comprising: a plurality of disks each having a rim with a circumferential blade root retention slot therein; a plurality of blades installed in each slot, each blade having an airfoil, a blade platform supporting said airfoil, and a root supporting said blade platform; said blade roots retained within said slots with said airfoils in high solidity relationship with each other; each blade platform having two circumferentially oriented ends, a first major axial edge portion adjacent a first end and substantially perpendicular to said first end, a second minor axial edge portion adjacent to the second end and substantially perpendicular to said second end, a canted intermediate edge portion intermediate said first and second axial edge portions; and said plurality of blades assembled with the minimum clearance between adjacent platforms occurring between said first major portions as compared to said second minor portions and said canted intermediate portions.
