See also:PARACHUTE (from Ital. parare, to See also:shield, protect; cf. " See also:parasol," " See also:parapet," and Fr. chute, a fall)
, an See also:instrument more or less resembling a large See also:umbrella, which by the resistance it offers to the See also:air enables an aeronaut attached to it to descend safely from a See also:balloon or flying See also:machine in the air
.
The principle of the See also:parachute is so See also:simple that the See also:idea must have occurred to persons in all ages
.
See also:Simon de la Loubere (1642–1729), in his See also:History of See also:Siam (See also:Paris, 1691), tells of a See also:person who frequently diverted the See also:court by the prodigious leaps he used to take, having two parachutes or umbrellas fastened to his See also:girdle
.
In 1783 Sebastien Lenormand practically demonstrated the efficiency of a' parachute by descending from the See also:tower of See also:Montpellier See also:observatory; but he merely regarded it as a useful means whereby to See also:- ESCAPE (in mid.

See also:Blanchard (1753–1809) is due the idea of using it as an See also:adjunct to the balloon
.
As See also:early as 1785 he had constructed a parachute to which was attached a See also:basket
.
In this he placed a See also:dog, which descended safely to the ground when the parachute was released from a balloon at a considerable See also:elevation
.
It is stated that he descended himself from a balloon in a parachute in 1793; but, owing to some defect. in its construction he See also:fell too rapidly, and See also:broke his See also:leg
.
See also:Andre Jacques Garnerin (1769–1823) was the first person who successfully descended from a balloon in a parachute, and he repeated this experiment so often that he may be said to have first demonstrated the practicability of using the machine, though his See also:elder See also:brother, J

Garnerin (1766–1849), also claimed a See also:share in the merit of perfecting it
.
In 1793 he was taken prisoner at Marchiennes, and while in captivity at See also:Bude (See also:Budapest) thought out the means of descending from a balloon by means of a parachute
.
His first public experiment was made on the 22nd of See also:October 1797
.
He ascended from the See also:park of Monceau, at Paris, and at the height of about i4 m. he
7eleased the parachute, which was attached to the balloon in See also:place of a See also:car; the balloon, relieved suddenly of so See also:great a See also:weight, See also:rose very rapidly till it burst, while the parachute descended very fast, making violent oscillations all the way
.
Garnerin, however, reached the See also:earth in safety
.
He repeated his parachute experiment in See also:England on the 21st of See also:September 1802
.
The parachute was See also:dome-shaped, and See also:bore a resemblance to a large
umbrella (fig

.
Garnerin separated the parachute from the balloon
.
For a few seconds his See also:fate seemed certain, as the parachute retained the collapsed See also:state in which it had originally ascended and fell very rapidly
.
It suddenly, however, See also:expanded, and the rapidity of its descent was at once checked, though oscillations were so violent that the car, which was suspended 20 ft. below, was sometimes on a level with the See also:rest of the apparatus
.
Some accounts state that these oscillations increased, others that they decreased as the parachute descended; the latter seems the more probable

Garnerin was hurt a little by the violence with which the basket containing him struck the earth; but a few cuts and a slight See also:nausea represented all the See also:ill effects of his fall
.
A few years later, Jordaki Kuparento, a See also:Polish aeronaut, made real use of a parachute
.
He ascended from See also:Warsaw on the 24th of See also:July 1808, in a fire-balloon, which, at a considerable elevation, took fire; but he was able to effect his descent in safety by means of his parachute
.
The next experiment made with a parachute resulted in the
See also:death of See also:Robert Cocking, who as early as 1814 had become
interested in the subject
.
The great defect of Garnerin's
umbrella-shaped parachute had been its violent oscillation
during descent, and Cocking considered that if the parachute
were made of a conical See also:form (vertex downwards) the whole
of this oscillation would be avoided; and if it were made of
sufficient See also:size there would be resistance enough to check too
rapid a descent
.
He therefore constructed.a parachute on this
principle (fig.2), the See also:radius
of which at its widest See also:part
was about 17 ft
.
It was
stated in the public an-
nouncements previous to
the experiment that the
whole weighed 223 lb;
but from the See also:evidence at
the See also:inquest it appeared
that the weight must have
been over 400 lb exclusive
of Cocking'sweight,which
was 177 lb
.

balloon, with See also:Charles
See also:Green, the aeronaut, and
See also:Edward See also:Spencer, a solici-
tor, in the car, and having suspended below it the parachute,
See also:PARADISE 751
in the car of which was Cocking, rose from See also:Vauxhall Gardens, London, at twenty-five minutes to eight in the evening
.
A See also:good See also:deal of difficulty was experienced in rising to a suitable height, partly in consequence of the resistance to the air offered by the expanded parachute, and partly owing to its weight
.
Cocking wished the height to be 8000 ft.; but when the balloon reached the height of 5000 ft., nearly over See also:Greenwich, Green called out to Cocking that he should be unable to ascend to the requisite height if the parachute was to descend in daylight
.
Cocking accordingly let slip the catch which was to liberate him from the balloon
.
The parachute for a few seconds descended very rapidly, but still evenly, until suddenly the upper rim seemed to give way and the whole apparatus collapsed (taking a form resembling an umbrella turned inside out, and nearly closed), and the machine descended with great rapidity, oscillating very much
.
When about 200 or 300 ft. from the ground the basket became disengaged from the remnant of the parachute, and Cocking was found in a field at See also:- LEE

Many objections were made to the form of Cocking's parachute; but there is little doubt that had it been constructed of sufficient strength, and perhaps of somewhat larger size, it would have answered its purpose
.
See also:John See also:Wise (1808–1879), the See also:American aeronaut, made some experiments on parachutes of both forms (Garnerin's and Cocking's), and found that the latter always were much more steady, descending generally in a See also:spiral See also:curve
.
A descending balloon See also:half-full of See also:gas either does rise, or can with a little management be made to rise, to the top of the netting and take the form of a parachute, thus materially lessening the rapidity of descent
.
Wise, in fact, having noticed this, once purposely exploded his balloon when at a considerable See also:altitude, and the resistance offered to the air by the envelope of the balloon was sufficient to enable him to reach the ground without injury
.
In more See also:recent times the use of the parachute has become fairly See also:common, but a good many serious accidents have occurred
