It is semi- aerobatic, the airframe was proof loaded to verify the stress calculations and no modification has ever been introduced since the prototype was approved.

Both R100 and R101 used a smaller number of longitudinal girders than previous airships in order to simplify stress calculations.

Shute's job was initially that of Chief Calculator, responsible for overseeing all the stress calculations needed.

Engineering work, stress calculations, and drawings for the first model, the KN-1, were completed in Room 623 of the Broadview Hotel.

One of his first efforts at the company were stress calculations for the Type 99 Badminton, a biplane racer being built for the 1926 King's Cup.

This being the case, some variation from the theoretical stress calculations should be expected in the field.

He'd personally checked every decimal place of the stress calculations, and he'd designed a safety margin of well over five hundred percent into the support structure.

He joined the Bristol Aeroplane Company in 1944 and was put to work on stress calculations of the Theseus engine.

Working to an outline design prepared with the help of data supplied by the NPL, the stress calculations were performed by Cardington.
