From Horatio Barber's The Aeroplane Speaks:


  • <note target>s from Chapter 1

    ...And the Principles gathered mournfully round, but with the aid of the Propeller Slip<note target="n1.1">[1]</note>
    <p>"Yes, indeed," spoke up the Propeller, "though it means that I must assume a most undignified attitude, for helicopters<note target="n1.2">[2]</note>

  • <note id>s from Chapter 1

    <note id="n1.1">[1] Propeller Slip: As the propeller screws through the air, the latter to a certain extent gives back to the thrust of the propellor blades, just as the shingle on the beach slips back as you ascend it. Such "give-back" is known as "slip," and anyone behind the propellor will feel the slip as a strong draught of air.</note>

    <note id="n1.2">[2] Helicopter. An air-screw revolving upon a vertical axis. If driven with sufficient power, it will lift vertically, but having regard to the mechanical difficulties of such construction, it is a most inefficient way of securing lift compared with the arrangement of an inclined surface driven by a propeller revolving about a horizontal axis.</note>


  • <note target>s from Chapter 2

    ...and a bewitching little Morane parasol,<note target="n2.1">[1]</note>
    He objects to skin friction,<note target="n2.2">[2]</note>
    ...and, in addition to that, there are the tricks I play with the Aeroplane when it's banked up,<note target="n2.3">[3]</note>

  • <note id>s from Chapter 2

    <note id="n2.1">[1] Morane parasol: A type of Morane monoplane in which the lifting surfaces are raised above the pilot in order to afford him a good view of the earth.</note>

    <note id="n2.2">[2] Skin friction is that part of the drift due to the friction of the air with roughnesses upon the surface of the aeroplane.</note>

    <note id="n2.3">[3] Banking: When an aeroplane is turned to the left or the right the centrifugal force of its momentum causes it to skid sideways and outwards away from the centre of the turn. To minimize such action the pilot banks, i.e., tilts, the aeroplane sideways in order to oppose the underside of the planes to the air. The aeroplane will not then skid outwards beyond the slight skid necessary to secure a sufficient pressure of air to balance the centrifugal force.</note>
