Two simplified versions of supersonic area rule

The simplified versions of the Jones formula, known as the supersonic area rule, which includes Jumper's simplification and four new proposed simplifications, are described. The Jones formula has been a major tool in the design and analysis of supersonic aircraft since its introduction. The Jumper simplification has been the first major modification of the standard supersonic area rule. Four new methods were developed, one of which provided interesting rules. The method uses cuts with the downstream Mach cone lateral surface on the equivalent body of revolution. The Jumper method proved superior to the new simplification at transonic and lower supersonic speeds.
