What was aviation as invented by Joseph and Étienne Montgolfier in 1783?

Ballooning (Hot Air & Hydrogen).

In what ways did the Motgolfier brothers and J.A.C. Charles finance their balloon experiments?

Government funding, publicity (Ticket) sales, and orders for mill, grants.

What was the military applications or uses of balloons?

Observe enemy troop postions and movement to report back to the commanders.

Why did balloonist ascend during the 19th century?


How are Balloons, Dirigibles, & Airships similar? Different?

They all use a form of gas to create an internal pressure les than outside pressure allowing flight.

Balloons have no rigid structure or direction control.

Dirigibles can be rigid or non-rigid and have powered directional control.

Airships are elongated, have multiple seperated chambers for gas, rigid, powered

directional controlled flight.

What makes a Balloon dirigible?

Controlled and powered flight.

Who was the Brazilian aviation pioneer who built and flew dirigibles and an airplane?

Alberto Santos-Dumont.

Why were lighter-than-air craft used in the artic?

To attempt to fly to the north pole.

Of the two sources pertaining to Walter Wellman that are listed in the bibliography, which one is a primary source and which one is a secondary source?

The Aerial Age is the primary source - because it is an autobiography of his life including letters, drawing, and photographs.

Who was the first to aeronautically identify the basic form and elements of a modern airplane?

Sir George Cayley

(late in the 18th century he defined the problem of mechanical flight {distinct from the chemical flight of balloons}: "to make a surface support a given weight by the application of power to the resistance of air." He also drew a diagram of the forces of lift, drag, and thrust; and he sketched a fixed-wing glider complete with vertical and horizontall control surfaces on the tail, a fuselage seat for pilot, and a manually operated "assisters" to propel the craft
