  Actual Lockheed SR-71 Blackbird TITANIUM and NICKEL ALLOY parts
                       [ The Lockheed SR-71 Blackbird history below ]

Welcome to Your SR-71 Blackbird Collectibles HeadQuarters


Dan Freeman Engineering INTRODUCES We are talking Rare Aviation Collectibles that are HAND
made presentations. ONE of a kind fabrications using AUTHENTIC / ACTUAL materials like TITANIUM and
SUPER EXOTIC NICKEL ALLOY [HASTELLOY-X]. Genuine parts from the historic Lockheed SR-71 Blackbird Aircrafts. products are the ultimate in aviation collectibles. is dedicated to make available at
affordable prices, small collectible pieces made from actual SR-71 Blackbird TITANIUM and NICKEL ALLOY parts.

These Titanium and Nickel parts were directly in the path of the giant Afterburners during many Top Secret Missions.
At nearly 35,000 pounds of thrust and at over 3,200 degrees, these parts were subjected to the most brutle conditions
of any jet aircraft in existance.

Think of it.. And you can almost feel the immense power of the Blackbirds massive J58 Turbo Bypass Jet Engines.
The Pratt & Whitney J58 was a Variable Cycle Engine which functioned as both a Turbojet and a fan assisted Ramjet.

Lockheed SR-71 Blackbird History in short..


The three last "Flying Amigos"..

Back in 1990 the SR-71 fleet was
decommissioned at Beale AFB.
Five years later, three of the
SR-71's were returned to back
to active service, at the cost of
$140 millions per year
to keep them flying.
The Air Force felt that
the money could be better used,
so the last three flying SR-71
aircrafts was taken out of service
again in 1995. Active service ends.


Demands in 1957 were to drawn up plans for a high flying reconnaissance spy plane. The CIA
was the backer behind the project. They wanted something that could reach anywhere in the
world in a matter of hours and have the photos lying on someone's desk by lunch.
The results was the Lockheed SR-71 Blackbird.

It was capable of an altitude of 90,000 ft. and Mach +3.2 speed, faster than a rifle bullet.
In 1968, the first SR-71s went into service at Kadena, AFB in Okinawa, Japan.
The SR-71s also operated out of two other bases: Beale Air Force Base, California
and Mindenthall, UK. Most of the missions were flown out of Kadena.

The plane was tough to land. Of the 32 Blackbirds built, 11 crashed on landing.
On the other hand, it was safe to fly. Over 1,000 attempts were made to shoot them
down, but not a single plane was lost to enemy action or mechanical problems.

In 1968, a presidential order required that all molds and tools used to build the SR-71
be destroyed so that the plane could never be built by anyone again. This also meant
that spare parts could not be made, so if there were any major problems,
planes in storage would have to be cannibalized.

In 1990,  the SR-71 fleet was decommissioned at Beale AFB. Five years later, three of
the planes were returned to service, but it cost $140 million a year to keep them flying.
The Air Force felt the money could be better used, so the plane was taken out of service.

The Pratt & Whitney J58 Ramjet - Turbojet design


The Ramjet - Turbojet design
Operation of the air inlets and air flow patterns through the J58 at different Mach numbers
The J58 is a hybrid jet engine: effectively a turbojet engine inside a fan-assisted ramjet engine.
This is because turbojets are inefficient at high speeds, yet Ramjets cannot operate at low speeds.
The airflow path through the engine varied, depending on whether Ramjet or Turbojet operation was
more efficient, thus the term [Variable Cycle]. Eg, at speeds over 2000 mph the nose cone of the
engine is pushed about 2 inches forward to improve the air flow in the Ramjet Cycle.


The Pratt & Whitney J58 was
a variable cycle engine which
functioned both as a fan assisted
Ramjet and Turbojet.


Air is initially compressed and heated by the shockwave cones, and then enters 4 stages of compressors,
then the airflow is split in 4: some of the air enters the compressor fans the main/core flow air, while
the remaining flow bypasses the core to enter the afterburner. The air continuing through the compressor
is further compressed before entering the combustor, where it is mixed with fuel
and ignited.  The flow
temperature reaches its maximum in the combustor, just below the temperature where the turbine blades
would soften. The air then cools as it passes through the turbine and re-joins the bypass air before
entering the Afterburner.

    J58 Airflows
 in various Mach's



At around Mach 3, the initial shock-cone compression greatly heats the air, which means that the turbojet
portion of the engine must reduce the fuel/air ratio in the combustion chamber so as not to melt the turbine
blades immediately downstream. The turbojet components of the engine thus provide far less thrust, and the
Blackbird flies with 80% of its thrust generated by the air that bypassed the majority of the turbomachinery
undergoing combustion in the afterburner portion and generating thrust as it expands out through the nozzle
and from the compression of the air acting on the rear surfaces of the spikes.

Dimensionless measuret for object going Supersonic


Mach is a dimensionless measure of relative speed. ? ? ?
It is defined as the speed of an object relative to a fluid medium,
divided by the speed of sound in the same medium. ! ! !

" The FORMULA 3+ "  M = V0 / VS  where:

M  is the Mach number, V0 is the velocity of the object relative to the medium and
VS is the velocity of sound in the medium

Did you grasp it, the main Thesis ??
