SUPER FAST Piasecki X 49A Helicopter for US Military
Helicopter The Piasecki X-49 is a four-bladed, twin-engined, experimental
compound helicopter under development by Piasecki Aircraft. The X-49A is
based on the airframe of a Sikorsky YSH-60F Seahawk, but utilizes
Piasecki's proprietary vectored thrust ducted propeller (VTDP) design and
includes the addition of lifting wings. The concept of the experimental
program is to apply the VTDP technology to a production military helicopter
to determine any benefit gained through increases in performance or useful
"SpeedHawk" is a concept aircraft based on applying X-49A compounding
concepts to a production UH-60 Black Hawk offering better performance,
range, and increases in useful load. The "SpeedHawk" aircraft includes an
SPU (third engine), high forward-swept wing concept, a 45 inch cabin
extending fuselage "plug", and several other drag reducing and
performance-oriented improvements, including a rotorhead fairing, landing
gear streamlining, and a fly-by-wire flight control system.
The U.S. Navy-sponsored project worth US$26.1 million consists of a
Sikorsky YSH-60F helicopter modified by Piasecki as a testbed to validate
the "Vectored Thrust Ducted Propeller" (VTDP) system. One YSH-60F was
converted to test the feasibility of VTDP under an advanced technology
demonstration program. The YSH-60F is powered by two General Electric
The demonstration contract was awarded on by the Naval Air Systems Command
to Piasecki Aircraft. Piasecki installed a lifting wing with flaperons and
a vectored-thrust ducted propeller (VTDP) to a U.S. Navy Sikorsky
The compound helicopter technology added to the YSH-60F was first
demonstrated in trials of the Piasecki 16H-1 and 16H-1A in the early 1960s,
when the helicopters were flown at speeds up to 225 mph (360 km/h). The
success of the Pathfinder inspired others to experiment with compounding,
resulting in programs such as the AH-56 Cheyenne.
In May 2003, the YSH-60F/VTDP demonstrator was redesignated the X-49A'.
During 2004, the X-49A VTDP program was transitioned from the US Navy to
the US Army.
Piasecki planned to use the vectored-thrust ducted propeller design of the
X-49 for their entry in the Future Vertical Lift program, but were not
chosen to take part in the Joint Multi-Role Technology Demonstrator
The X-49A flight demonstrator is being developed with funding from the US
Army's Aviation Applied Technology Directorate to demonstrate the ability
to increase the speed of existing helicopters to 200 kt (360 km/h) or
more. The flight demonstrator has been updated with a lifting wing taken
from an Aerostar FJ-100 business jet. A ring tail has been added and the
helicopter drive train modified to accommodate VTDP. Piasecki conducted
integrated tests of the modified drive train at the Navy's helicopter
transmission test facility. The wings are intended to produce lift to
offload the rotor so the rotor can be slowed down and produce less drag,
allowing for higher speed.
The cockpit controls are modified with the addition of a manual prop pitch
override on the collective for the ring tail. This is the only visible
change to the aircraft's existing mechanical controls in the cockpit. The
other controls needed to operate the compound helicopter's systems are
integrated into the aircraft's existing mechanical controls to reduce pilot
workload. The weight added to the X-49A demonstrator aircraft is estimated
at about 1,600 lb (725 kg) due to the requirement to not
modify the existing mechanical control system.
The X-49A made its first flight on June 29, 2007 for 15 minutes at
Boeing's New Castle County (KILG) flight test center. This flight
included hovering, pedal turns, and slow forwards and sideways flight using
the VTDP for anti-torque, directional and trim control. The X-49A has
completed its initial testing phase, and is continuing with further testing
of the technology. Since then, it has flown over 80 flight
events with more than 80 total hours logged.
A helicopter is a type of rotorcraft in which lift and thrust are supplied
by rotors. This allows the helicopter to take off and land vertically, to
hover, and to fly forward, backward, and laterally. These attributes allow
helicopters to be used in congested or isolated areas where fixed-wing
aircraft would usually not be able to take off or land. The capability to
hover efficiently for extended periods of time allows a helicopter to
accomplish tasks that fixed-wing aircraft and other forms of vertical
takeoff and landing aircraft cannot perform.
The word helicopter is adapted from the French language hélicoptère,
coined by Gustave Ponton d'Amécourt in 1861, which originates from the
Greek helix/helik- (ἕλιξ) "twisted, curved" and pteron
(πτερόν) "wing". English-language nicknames for helicopter
include "chopper", "helo", "heli" and "whirlybird".

Amazing Helicopter Flying, Car Chase
This video exposes the low level helicopter flying done to chase cars for
the amazing footage you may see in a film or on TV. It's real life Grand
Theft Auto, no CGI, no fake stuff!
The truck I am in is a real real bone shaker, it was hauling a full size
trailer and that chopper comes very close to the trailer when passing. I
never felt easy about how close it was to the truck.
Has to be some of the most impressive flying I have seen, luckily I grabbed
some good video of the amazing low level flying. Pilot Gary Ticehurst.
You can see the work Gary did via this link.
Sadly Gary passed away in a Helicopter crash in 2011.
This is a Nissan car commercial from the late 90's, and the director Mr
Peter Cherry is recreating a scene from the film 'The Deer Hunter' where a
car does a risky overtaking move on a truck leaving an industrial site.
TNT 737 Crash Landing at Birmingham UK
Here is video of the 'TNT' 737 crash-landing at Birmingham Airport (EGBB)
This landing happened after the aborted attempt at Nottingham East
Midlands, where the right main undercarrige was ripped off and took out the
flaps on the right wing. The aircraft is presently sitting on the unused
runway at Birmingham Airport and can be seen from the golf course nearby.
(So my cousin informs me!)
Filmed by a news helicopter that was in the area and handed over to the
local Police and Investigation Team, this is probably the best footage of
an incident like this I have seen.
THE WORLDS BIGGEST PLANES!! by kieran smith
http://www.youtube.com/watch?v=8VzgbjtTDww The Antonov An-225 Mriya,(THE
WORLDS BIGGEST PLANE) (NATO reporting name: Cossack) is a strategic airlift
transport airplane that was built by Antonov (ASTC). It was designed for
the Soviet space program as a replacement for the Myasishchev M-4 'Bison'
for the purpose of carrying the Energia rocket Boosters and to also be able to carry the
Buran space shuttle in piggy-back mode much the same as the American
Shuttle Carrier Aircraft.The An-225 first flew on 21 December, 1988. Only
one An-225 is currently in service. It is commercially available for
carrying ultra heavy and/or oversize freight. It can carry up to 227 metric
tons (250 short tons) of cargo. A second An-225 was partially built in
connection with the Soviet space program but was never finished. This unit
is finally nearing completion as of 2005. The construction of further units
will depend upon demand for oversize cargolifting.At 600 metric tons, the
An-225 is the world's heaviest aircraft, although its wingspan is less than
that of the "Spruce Goose", Howard Hughes' flying boat, which never flew
more a single, short, low-altitude test flight. Both the An-124 and An-225
are larger than the C-5 Galaxy, the largest aircraft in the U.S. inventory.
The An-225 is also larger than the Airbus A380. In November of 2004, FAI
placed the An-225 in the Guinness Book of Records for its 240 records and
overall outstanding aerial performance.The funniest 6 minutes you will ever
see! Remember how many of these you have done!

Swedish Helicopter Crash
6/21/05 - STOCKHOLM, Sweden
I got this footage from last week. In the paper they say the "video showed
the rotor blades of the Lithuanian-registered MI-2 helicopter hitting a
tree, then clipping the top off a lamp post."
I never noticed the lamp being cut down, but you can clearly see it if you
focus on it. This was the guy's birthday present, a helicopter ride!
Instead he got a helicopter ride to the hospital.
Awful accident in Colombia
The video was presented by Noticas RCN, a news segment from Canal RCN of
The plane was operated by Patrulla Aérea Colombiana (Colombian Air
Patrol), a non-profit organization that helps people with medical
assistance on remote places of Colombia.
There was 4 people on board: The pilot and chief of medical staff, another
doctor, a little boy recently operated, and the mother of the boy. All died
instantly except the pilot, who died a few day later due to the extensive
burnings on his body.
May all they rest in peace.

Helicopters were developed and built during the first half-century of
flight, with the Focke-Wulf Fw 61 being the first operational helicopter in
1936. Some helicopters reached limited production, but it was not until
1942 that a helicopter designed by Igor Sikorsky reached full-scale
production, with 131 aircraft built. Though most earlier designs used
more than one main rotor, it is the single main rotor with anti-torque tail
rotor configuration that has become the most common helicopter
configuration. Tandem rotor helicopters are also in widespread use, due to
their better payload capacity. Quadrotor helicopters and other types of
multicopter have been developed for specialized applications.
