Airspeed, Ltd., rier Airport, Portsmouth TEIS new machine—not yet through its trials—is in quite a different class from the Ferry (described in this paper on March 3), having been developed as a low-wing monoplane of particularly clean design with a retractable undercarriage hydraulically operated. The wind resistance created by the undercarriage is much greater than might be expected.
The accompanying estimated performance data are based on the Armstrong Siddeley Lynx engine, but a choice of several engines is available. By fitting extra fuel tanks the range can be increased to 780 miles and, as the cruising speed is 130 m.p.h., this is likely to represent a useful machine for real timesaving cross-country air services.
Further details will be published when trials have been completed.
