Some tests were performed with a casing construction that could incorporate pad mounted motors particularly useful in smaller Tunnel Jet Fans where advantage can be taken of improved aerodynamic conditions within the fan casing. Tests 3 and 4 were used to certify the foot mount range with deep grove ball bearings. Proving the high temperature capability of the range provided a challenge as a consequence of the large physical sizes and high motor powers involved. Portoroz, Slovenia, 11—13 July, pp. The original range Tests 2—7 was tested with pad-mounted motors as they provided for the most cost effective and aerodynamically sound fan construction, although the maximum available motor frame size was Secondly to certify deep grove ball bearings with foot mounted motor construction for horizontal application, Fig.
