today we're exploring concept aircraft
0:05
the futuristic designs that push the
0:07
boundaries of aviation as we know it
0:10
these aren't just dreams they're
0:11
glimpses into the future of
0:16
flight on October 14th 1947 the bullet
0:21
shaped Bell X1 secured its legacy in
0:23
aviation history as Captain Charles E
0:26
chuck Joerger became the first person to
0:29
break the sound barrier in a documented
0:31
and successful supersonic flight
0:33
initially designated the XS1 standing
0:36
for experimental supersonic the X1
0:39
marked the beginning of a line of rocket
0:41
powered Xplanes that Joerger and other
0:43
test pilots would use to explore new
0:45
frontiers of speed and
0:48
altitude the X1 did not use a
0:50
traditional runway takeoff instead it
0:53
was transported to high altitude inside
0:55
the bomb bay of a Boeing B-29
0:57
Superfortress at the designated height
1:00
the X1 was released like a large bomb
1:03
free falling away from the B-29 before
1:05
the pilot activated the rocket engine
1:08
propelling the aircraft rapidly upward
2:16
french engineer Renee Leuk achieved his
2:18
initial breakthrough with ramjet
2:20
propulsion in 1935 successfully
2:23
operating a functional engine that
2:26
0.039 kons of thrust his work resumed
2:30
after World War II and by 1949 the first
2:34
0.10 ramjet powered aircraft took flight
2:37
after being launched from a Langodok
2:39
airliner the project advanced through
2:41
the early 1950s culminating in the 0.22
2:44
22 MAC 2 interceptor prototype although
2:47
this high-speed aircraft flew
2:49
successfully progress stalled due to
2:51
insufficient financial
3:50
undeniably innovative the X19 was
3:53
developed to explore the use of tilting
3:56
propellers for achieving vertical
3:57
takeoff and landing capabilities this
4:00
unconventional aircraft originated as a
4:03
private project by the Curtisright
4:04
Corporation a former aircraft
4:06
manufacturer that had shifted its focus
4:09
to engine technology by the 1960s
4:12
designated an experimental Xplane by the
4:14
US Air Force the X19 underwent a 2-year
4:18
flight test program that significantly
4:20
advanced VTOL research
5:18
the Ferry Delta I was among several
5:20
groundbreaking aircraft to appear during
5:22
the fast-paced evolution of postwar
5:24
aviation it was the first British
5:27
supersonic delta-wing aircraft and the
5:29
first to feature a drooping nose to
5:31
enhance pilot visibility at lower speeds
5:34
a design later used on the Concord
5:36
beginning in 1954 two Delta I prototypes
5:39
undertook a series of research flights
5:42
producing a vast amount of data that
5:44
would inform the design of future
5:46
military and civilian
6:44
developed to operate from the Soviet
6:46
Navy's key of class aircraft carrying
6:48
cruisers as a successor to the Yak 38
6:51
Forgger the Yak 141 made its first
6:54
flight in March 1989 it featured an
6:57
innovative design combining a powerful
7:00
main engine with two auxiliary lift jets
7:03
the aircraft's vectoring nozzles allowed
7:05
for vertical takeoff during standard
7:07
flight it was capable of reaching
