  01-07-1872 : Born in Cambrai.
bleriot_I_1900-1901_500.jpg (29662 bytes) 1902    Bleriot I
Apparently a model as it spanned only 1.5 meters.
Powered by a CO2 engine of 2 hp.
Has never flown; was handed over to the Musee de l'Air in 1937 and has since disappeared.
bleriot_cvoisin_1905_1_350.jpg (42674 bytes) 1905
Louis Blériot meets Gabriël Voisin. The start of a promising cooperation.
bleriot_II_jul05_500.jpg (40079 bytes) 1905    Bleriot II
Glider on floats to be towed by a speedboat with an Antoinette engine. Testflying over water was considered safer in those days.
Biplane with boxkite tailsurfaces. Upper wing has greater span than lower one.
The airframe was designed by Voisin but Bleriot attempted to influence him in many ways, hence the strongly curved wing section.
Made only one start wich failed and has never managed to fly.
  1906 Participation in the enterprise of Levavasseur, the S.A. Antoinette.
bleriot_III_1_500.jpg (65444 bytes) 1906    Bleriot III.
Powered airplane with elliptical tandemwings and equipped with floats. 
Double elevators,positioned behind the propellors.
Propulsion: twin propellors, driven by a 20 hp Antoinette engine through a reduction gearing. The engine was built on special order with a bore and stroke of each 80 mm.
Weight drive train/gearing 110 kg. Total weight of airplane 400 kg.
May 1906: Tests conducted by Louis Peyret proved unsuccesful: it would not leave the water.
bleriot_IV_oct06_500.jpg (35895 bytes) 1906    Bleriot IV
Modification on Bl. III. Front wing replaced by a boxkite type wing. 
Ailerons mounted on struts between the front wings.
Rear tandem wing equipped with a rudder. Double elevator mounted in front of front wing.
Twin pusher propellors, each driven by a  24 hp Antoinette motor (8 cyl.) through a gear reduction. Total weight 480 kg.
October: tested on floats, results nil.
bleriot_IV_nov06_500.jpg (30038 bytes) 1906    Bleriot IV
12 november: Tested on land (Bois de Boulogne): got severely damaged after it struck an obstacle.
An attempt was made to rebuild it with with a single 50 hp Antoinette engine but it was never completed.
Thus ended the partnership with Voisin.
  1907
Start of a new enterprise: L.Bleriot Recherches Aéronautiques in Neuilly, dedicated to the design and construction of aeroplanes.
bleriot_V_janmar07_500.jpg (33848 bytes) 1907    Bleriot V
And now for something completely different!
Monoplane in canard configuration. Driven by a 24 hp Antoinette engine.
Weight (incl pilot) 236 kg.
21-03: primary test: considerable damage through collapsing undercarriage. Subsequent tests with similar results.
bleriot_V_mod_apr07_500.jpg (32154 bytes) 05-04-1907
The first leap has been made; a "flight" of 5 to 6 meters.
bleriot_V_mod2_apr07_500.jpg (39601 bytes) 19-04-1907
Because of a hard 'landing' the plane gets seriously damaged.
bleriot_VI_jun07_500.jpg (40086 bytes) juni 1907    Bleriot VI. the "Libellule"
Tandem layout. Strong dihedral on both wings.
Elevons mounted on front wing. Rudder between two vertical fins (top and bottom). 
Propulsion: conventional propellor with 24 hp Antoinette engine.
11-07: first flight of ± 30 meter, aborted because of pedestrians crossing ahead. 25-07: flight of 10 sec. and ± 150 meters with changes of direction. 
Modifications: less dihedral in front wing and no dihedral in rear one. 16-cylinder Antoinette of 50 hp. 4-bladed metal propellor.
17-09: testflight with fixed elevator(!). When the engine failed a nosedive followed suit leading to a crash landing. 
Duration of this flight 17 secs, distance 184 meters. Longest European flight sofar.
bleriot_VIb_augsep07_500.jpg (26654 bytes)
bleriot_VII_750.jpg (34995 bytes) 1907    Bleriot VII
Lowwinged monoplane. Covered fuselage, large stabilizer with elevator.
4-bladed prop, driven by a 16-cylinder 50 hp Antoinette.
Undercarriage suspension to prevent damage on landing.
Later modifications consisted of placing the wing higher and introducing a cabane for bracing wires on the wing.

06-12: two flights of 500 meters. U-turn executed.
18-12: undercarriage gave way on landing: airplane overturned and was destroyed. 

bleriot_VII_mod2_dec07_500.jpg (33678 bytes)
bleriot_VIIIbis_jun08_500.jpg (24790 bytes) 1908    Bleriot VIII
Follow-up on Bl VII, in various layouts concerning placement of the ailerons.
After a crash the machine was rebuilt, which hitherto had never occurred.
The picture shows the VIIIb (bis), therefore presumably the rebuilt machine.
bleriot_VIIIt_augnov08_500.jpg (18720 bytes) 1908    Bleriot VIIIt
The third version of the 'VIII'.
31-10: Bleriot used this machine to fly from Toury to Artenai and back, admittedly with intermediate stops but with 28 km the longest overlandflight ever.
bleriot_IX_feb08-mar09_500.jpg (42201 bytes) 1909    Bleriot IX
Follow-up on the 'VIII'. Never passed the testing stage.
bleriot_X_sepdec08_500.jpg (38503 bytes) 1909    Bleriot X
A complete change of fashion with regard to all of its predecessors. This is a Wright style biplane intended for four(!) persons.
Was put on display at the Salon de Paris but has never flown.
bleriot_XI_rep_no08apr09_500.jpg (21330 bytes) 1909    Bleriot XI
Start of the success story for Louis Bleriot.
Further development on Bl. VIII. Wingwarping for lateral control was introduced here in favour of aileron control.
23-01: first flight on Issy-les-Moulineaux, still with the REP engine.(Robert Esnault-Pelterie)
15-03: testflight of 2500 meter with REP engine 
bleriot_XI_anz_mayjun09_500.jpg (24109 bytes) 1909    Bleriot XI
27-05: Introduction of the Anzani engine: 3377 cc, 3 cylinders, bore 105, stroke 130 mm. The successes are flowing in:
26-06: Issy, 36 min 55 sec.
04-07: Juvisy, 50 min 8 sec.
13-07: Prix de Voyage, 41,2 km from Etampes to Orléans in 44 min 30 sec.
With these achievements the Channel crossing has become a real possibility.
