HADI-9 is a Soviet turbojet from the HADI series, designed and built to establish an absolute speed record on land [1] . The only car in the USSR of this type.
I did not participate in record races, was tested at the airport and on the salt surface of the drying lake Baskunchak . He starred in the film “Speed” called Needle-09-SR [2] .

Specifications
Length 11 m.
Height 1.1 m.
Weight 2500 kg.
The estimated speed of 1200 km / h.
The power unit is an RD-9 BF turbojet engine.
Engine thrust 5500 kgf [1] . According to other sources, the RD-9 engine had maximum thrust in afterburner mode up to 3800 kgf [3] .
The car had a streamlined cigar-shaped shape and was generally similar to the first FAU-2 ballistic missiles , only instead of four it had one stabilizer and moved parallel to the ground on wheels.
The outer casing is made of fiberglass on a metal frame. The wheels had a hydraulic suspension. The rear wheels were located on the outer rods far from the body to improve stability on the track of an overly narrow car, as well as for additional aerodynamic stabilization at high speed. Two front wheels were inside the streamlined body behind the cockpit. Braking was carried out by the sequential introduction of air dampers, increasing air resistance, and then a parachute . It was also possible to reverse the aircraft engine [1] .
Creation History
In the late 1960s, the laboratory of high-speed cars of the Kharkov Highway Institute was set to achieve a speed of 1000 km / h, at that time not yet taken by American and English competitors. Design and construction of the car began in 1968, led the project by Nikitin Vladimir Konstantinovich .
After the record race of the American Blue Flame car on the Bonneville salt plateau at a speed of 1014 km per hour in 1970, engineers began to prepare the car under construction for another more significant speed limit - overcoming the sound barrier of 1190 km / h. They hoped to gain the required speed of 1200 km / h due to the lightweight body and forcing the aircraft engine.
Pilots of the car doubted the reach of the milestone of 1000 km / h and even more so the speed of sound, since the car did not have sufficient thrust-weight ratio. The RD-9 engine without boost developed thrust up to 2800 kgf, with boost up to 3800 kgf, while the same record Blue Flame car of a similar size had a rocket engine with a thrust of 5900 kgf and was barely able to cross 1000 km / h [4] . But the ceiling of 700-800 km / h was considered quite real.
In 1978, HADI-9 visited the exposition of VDNH in Moscow [5] .
Due to the lack of a suitable track and the necessary funding, no attempts were made to set a speed record on it and the finished car stood in the garages of the Kharkov Highway Institute for several years.
Testing and filming a movie
For adequate testing of such a car and reaching maximum speed, you need a straight and very smooth track with a length of about 10 kilometers. The only place in the USSR where such a route could have been equipped at minimal cost was the salt bottom of the drying lake Baskunchak , similar to the American Bonneville lake , where most record rides take place. Existing aviation airfields and automobile test sites are too short for this. But in 1963, due to increased salt production, all races on this lake were stopped and its bottom turned into a quarry. Artificial routes of this length were not built. Therefore, the maximum speed at which HADI-9 was capable remained unknown.
Short test races took place at airfields in Chuguev and Volgograd and in the remaining undisturbed sections of Lake Baskunchak during the filming of the film "Speed" and were paid from the filming budget [6] . According to the director Dmitry Svetozarov , when shooting the film “KhADI-9”, they were tested twice on the runway of the Kiev military airfield, while the speed reached about 300 km / h [7] . According to unconfirmed reports, the car developed a speed of about 400 km / h. Also, according to Svetozarov, a group of stuntmen, without announcing the rest of the film crew and designers, once dispersed a jet wagon to 500 km / h [5] .
After the shooting, the car was brought back to Kharkov , where they left it for a long time without leaving, forgetting even to wash. Baskunchak salt, not removed from the body and internal parts, caused intense corrosion of light metal structures and rapid destruction of the machine [8] .
