The following extract may give an
indication as to George Prensiel's motives in developing an "aerial safety
device"

The Times,
May 28th 1912
reported that following a speed contest held at London
Aerodrome, Hendon, that was declared void due to the
numerous accidents caused by the gusty conditions, "Shortly
after the contests had finished Mr. Prensiell, in a Bleriot
monoplane, went out for a flight. Mr. Turner was also in the
air on his biplane. When flying on the further side of the
Aerodrome at a height of about 100ft. Mr. Prensiell's
machine caught the back-wash of that of Mr. Turner and fell
to the ground. Mr. Prensiell was pinned underneath
sustaining a fractured leg. He was removed to hospital. |

Un nuovo
paracadute
In Inghilterra e stato provato un nuovo paracudute per
aviatori, che presenta partico lari originali degni de
rilievo.
Quando e dhiuso il paradute occupa uno spazio brevissimo,
pur essendoe facisilsimo lo spiegamento. Questo viene
effettuato da un tubo d'alluminio ad aria compressa che puo
esser fatto funzionare dal pilota, per cui paracadute
funziona a qualsiasi altezza, anche piccola, mentre quelli
finora inventati avevano bisogno di uno spazio di caduta piu
o meno grand per potersi spiegare a funzionare
L'inventore e Mr
George Prenciel.

Life-saving Parachute Apparatus for use in Aerial Navigation
Patent No. 16,943
On 23rd July, 1913 George
Prensiel, an Aviator Engineer, working at the London
Aerodrome, Hendon, N. W submitted a patent application ".
. . for use in saving life in connection with aerial
navigation: the chief object being to ensure the safety of
the airman in the event of an accident occurring to the
machine or air craft during flight."
The device was intended on
the activation of the pilot to rapidly release by compressed
air a parachute from a cylinder situated within the
fuselage of the aircraft immediately to the rear of the
aviator's seat. The aviator would be pulled from the
aircraft to safety upon the expulsion of the parachute.
A year later Prensiel put
his compressed air parachute extraction system to the test.
Fired from the rear of a moving vehicle the parachute was
successfully propelled from its tube. |

the
following was reported in Flight, 21st August 1914
'There have been a lot of German spy
stories about lately and also many unconfirmed rumours but
whether the following is one of the latter I am not certain.
It is said that a certain person informed the police that he
had a German lodger whom he not only believed to be a spy
but who had an infernal machine in his room. The police
thereupon acted promptly, arrested the "spy", cleared
everybody from the house out of danger and bravely put the
infernal machine under water. The "spy" was none other than
George Prensiel and his bomb was his very ingenious life
saving parachute . . . '

Flight JULY 31, 1914. THE PRENSIEL LIFE‑SAVING PARACHUTE.
THERE have been many advocates of the parachute as a means
of saving life is case of accident to an aircraft, but this
aspect of the problem has presented one or two difficult
propositions that are not easily got over. Pegoud and others
have demonstrated that it is possible to descend from an
aeroplane by means of a parachute, but these descents have
been made under prearranged conditions, whilst the recent
fatal accident to Mine. Cayat de Castella has shown that the
danger of the parachute not opening is a serious
contingency. It is this latter problem at which George
Prensiel‑who obtained his pilot's certificate in January,
1912, and for some time flew a Blériot at Hendon‑bas been
working for the last two or three years, and has, he claims,
just produced an apparatus which will not only fully open
the parachute at the desired moment, but will force the
parachute and whatever is attached to it well clear of the
aircraft. Briefly, the Prensiel apparatus consists of a
steel cylinder containing compressed air at a high pressure,
which is suitably mounted on the aircraft. Connected to this
cylinder is a vessel in which is packed the parachute, which
is attached to a movable seat occupied by the pilot. On
opening a valve, the compressed air is admitted to the
vessel containing the parachute, which is shot out of the
container with some considerable force, opening fully
immediately, and carrying the pilot and seat with it leaving
the machine to look after itself. A general idea of the
apparatus can be obtained from the accompanying
illustration, which shows Mr. Prensiel's latest model. The
whole apparatus is exceptionally light, weighing only about
30 lbs., and is so constructed that it can easily be fitted
to most modern machines. That it works successfully so far
as expelling the parachute, opening the same, and lifting
the weight of a man is concerned has been satisfactorily
demonstrated on several occasions, and further developments
will be awaited.with interest |
