Lazarov two little known aircraft

Hi,

this Bulgarian designer was developed two little known aircraft,but not built,
LAZ-9 a two seat trainer and light attack aircraft of 1950 and powered by
one 450 hp Argus As-410 engine and LAZ-14 a two seat jet trainer aircraft
powered by one Turbomeca Marbore II turbojet engine and estimated speed
was 610 km/h, it was designed in 1958.

My dear boxkite,

the Laz-10H was a helicopter but I cann't find any data about it.

Anyone here with access to JAWA 1957-1958? I found a notice on my harddisk that an LAZ-10H entry is on page 128, but I have no scan or Xerox copy . Must be a design with gas turbine(s) or tip jet engines.

My dear boxkite,

I find a small informations about LAZ-10H; it was lightweight two seat single
rotor helicopter and had a top speed 120 km/h,but no information about the
engine.

The LAZ-10H is a lightweight single-rotor helicopter, seating two side by side in an enclosed cabin. It is powered by two pulse-jet engines, mounted on the tips of the two-blade rotor. The rotor blades can be folded and the tail-boom removed for transport. Re-assembly of the helicopter takes ten minutes.
Weights estimated empty 155kg loaded 420kg
Performance estimated Max speed 120km/h, cruising speed 100km/h, service ceiling 4,000m, hovering ceiling 1,200m Endurance 1 hr.

Thanks .

dear hesham Ivan Borislavov stated in his book:
"The remaining copies of the drawings, the aircraft received the designation Laz-14,
have a date of June 26, 1958. This means that work on the project began much earlier."

Have a nice day Petko

Thank you dear Piko 1,

Lazarov LAZ-11 was a single engined cabin monoplane,
used as ambulance version of LAZ-8.

i think that you are speaking about the Laz-12 witch was developed using most of the parts and aggregates of Laz-7m
Laz-8 was only one plane and it was made as a gift for Giorgi Dimitrov ( Civ.Reg: LZ-BKP )

more information on Laz - 14

again quote from Ivan Borislvov this one is from the Airgoroup2000 forum :

"On October 10, 1950 Mr. Lazarov sends a confidential letter to the Air Force command and unification "Metalhim", whose composition is in airplane industry, the creation of training propeller aircraft Laz-9 for the increased needs of Bulgarian aviation.
The proposal was not adopted as one of the arguments that is time of the jet aviation.
In 1952 Prof. Lazarov started as a private initiative working on several versions of jet training aircraft using the developments of French and Italian aircraft manufacturers SIPA, Potez, Caproni at that time.
Laz-14 project is ready end of 1956
The documents disappeared in 1959
Prof. Lazarov died in January 1961"

Have a nice Day
Petko

Ps. there are some speculations about the documents that were stolen and used for basis of the TS-11 "Iskra"
