Design notes for the combined roll, tilt, and vertical hydraulic suspension for the A.P.T. (IM-DYN-016)

These notes describe a particular realisation of the APT suspension scheme described in IMD/4 (R/APT/137). The IMD/4 scheme had a passive lateral suspension below a tilting actuator, which tilted the body about a pivot below its floor. While curving, the combined effect of the lateral displacement on the lateral suspension...
