In the late 60’s the Indian
Government set out a requirement for a Helicopter that could fly in “Hot and
High” climates. Aérospatiale submitted a Helicopter based on their Successful Alouette
II. The Alouette II first flew in
1955 and was being replaced by the heaver more powerful Alouette III. The submission of the new Helicopter would
be a blending of these two proven rotorcraft.
The SA 315B Lama would use the
smaller airframe of the Alouette II.
The airframe however was reinforced and strengthened. To that airframe was mated the Alouette
III power plant the Turbomeca Astazou IIIB. The IIIB originally rated at 870
Shaft Horsepower it was down rated to 550 Shaft Horsepower. The lighter airframe mated to the more
powerful engine gives the LAMA gives the ability to carry up to 4 people or a
maximum of 2,500 pounds of slung payload.
The new helicopter was first
flown on March 17, 1969 piloted by Roland Coffignot and Gerard Boutin. It would get its French airworthiness
certificate in 1970. In 1971 HAL,
or Hindustan Aeronautics Limited received the license to produce the LAMA as
the Cheetal. The HAL version first
flew on October 6, 1972. Helibras
of Brasil received a license in 1978 for production of the LAMA it is called
the Gavião.
India primary uses the Cheetah
for patrols and Search and rescue in the Himalayas. Launching from Bases as high as 24,600 Feet. That’s 4.65 miles high. India also has created an armed version
called the Lancer. The Lancer
incorporates, up-rated armour plate and has two pods carrying a 12.7mm machine
gun and three unguided rockets.
The Lancer has a redesigned “bubble” for reinforcement and better visibility. For self-defense it has the addition of
Flairs and Chaff.
The LAMA is to operate in extreme
climes. To prove this Aérospatiale
wanted to originally land a LAMA on top of one of the Himalayan Mountains
however it not given permission by the India Government. Aerospatiale decided on setting some
records. In 1969 a crew of two
with 260 Lbs of fuel took off and then landed at the then highest recorded
altitude for a helicopter 24,605 feet above sea level. I might add that this has become routine
for this helicopter.
On June 21, 1972 Jean Boulet took
off solo in a modified SA 315B, the airframe had all of the interior removed
except for the necessities for the pilot. He began is assent into the record
books. Boulet a trained Engineer and Test pilot climbed his Lama to the still
unbroken absolute height of 40,814 Feet.
Boulet upon reaching that
altitude began to throttle back the Turbo Engine only to have a the
engine flame out. Boulet then
began another record, albeit an unexpected one. Boulet autorotated, for over 30 minutes, until he safely
landed. This is the unofficial
world’s longest autorotation. It
can never be official because it wasn’t planned for or officially
documented.
In 2009 HAL reopened their line
and started producing the Cheetah with the new Turbomeca TM 333. A single engine version, of the power
plant, that drives the Dauphin and Panther helicopters.
Aérospatiale has produced 447
Lamas
