This book deals with problem confronting deeigaers of & all-sized
gyro equipsaart for use in airplanes, t-ka, sn4 high-speed cutters.
The author notes that experimehtal data on this subject is far from
adequate.. Without attempting a complete coverage of gyro the'ry (al-
reedy done by other authors), he states that his sins are to systema-
tize gyro design practices, recu end starting points in the planning
'agee, reduce to a con syetea data previously published in little
M
known journals, and develop over-all criteria for designing small-sized
gyro equipment.
he book has been approved as a textbook for aviation institutes and
contains numerous photographs, sketches, and graphs to clarify the, text,
vhiclr frequently presents mathsmtical relatianslips of ph7eical concepts.
