This article describes a new suspended hovertrain design known as the bliss pendair system. The vehicle is suspended from a precast concrete box beam track. Portal frames support the track. The problems of detecting obstacles on the track and the effect of snow and ice are minimized in the enclosed track. A suction air cushion generated by a fan is formed between the platform from which the vehicle is suspended and the adjacent inside track surfaces. The platform rotates about its longitudinal axis to form a pendulum suspension which allows for the negotiation of tight curves at speed. The project, backed by a civil engineering contractor, has led to the manufacture of arbitrarily curved beams in a flexible mould. A model of the pendair system and its design detail's are given. It is envisaged that the pendair system will provide rapid urban and suburban transport with a top speed of 100 km/hr although it would be suitable for 500 km/hr vehicles. /TRRL/
