Various Grokhovski Projects

[Stargazer]

What was this,I can't ID it well,and I have a drawing to flying tank by Grokhovski ?,I know the translation
said : it was imagine from the author,but was it real ?

Looks like a pilotless version of the G.37.

G-48
Design for a maritime Aerobus to be dropped by a Tupolev TB-1 as very low level. The container doubled as a motorboat with a capacity for 14 troops and a Maxim machine-gun. Tested briefly until destroyed when making contact with the water.

G-68
Design for a cabin to be dropped, at low level, with no parachure. Project was known as the "Summer Aerobus". It was described as being a short wing with a thick aerofoil and had a pair of aircraft wheels at the front and a pair of metal skids and shock absorbers at the rear. Then released from the mothership it was to glide at a steep angle and land on its wheels. It was envisaged that this delivery method would be used in the first stage of an air assault. Could carry four passengers, tested at least twice on land, no people on board, with a successful outcome. Once P.I. Grokhovski and I.V.Titov allegedly trialed the device in flight. Titov suffered loss of consiousness for a short period but both survived!

Here is a Gokhovski G-68 & G-48.

The heavy transport glider G-64 (Designer B.Urlapov) - can accommodate fifty people, so to speak, was a multiple increase in the centerplane G-63. The designer really justifies the possibility of creating a whole aero-trains. By the powerful four-engined aircraft are fixed not one or two but eight gliders. Thus, one plane throws to the back of the enemy of 400 paratroopers. Precise data on the airframe not.
Also, little information is retained on the tow plane.
Transport and combat aircraft -universal/wagon. (presumably the designer V.Rentel)
Identification is not known.
It was supposed to use the plane in five or six versions, Suspended cabine for various purposes: cargo, passenger, paraborne, agitation/propaganda and military, armed with four machine gun turrets and bomb racks ...

Your work are amaizing, borovik!!!

Hi folks,
Pardon a cross-threaded post but I posted some more stuff on the Grokhovski G-39 "Cucaracha" in this thread here: http://www.secretprojects.co.uk/forum/index.php/topic,3667.msg277204.html#msg277204
Thanks, 'Wingknut'

Grokhovski Horizontal Triplane Project

I came across this weird looking Grokhovski design artwork in "Unflown Wings".

It was described in the text as a project for a "Three-engined aircraft of horizontal triplane configuration".

Powered by just three V-12 engines and with a fixed undercarriage with three sets of wings, a triplane but not as we usually know it.

There were two separate cockpits with innovative carriage of 40+ passengers/troops in individual integrated pods within the wings. This would be similar to the people pods fitted at one stage to the Polikarpov R-5, a modification also undertaken by Grokhovski.

The fuselage looks remarkably flimsy and the design is worthy of a "Heath-Robinson" design.

I doubt this project got much further than the artwork stage but goes to show the active imagination once again of Grokhovski.

The G-37 & G-39 in colors.

While looking for some Bartini details I found this images that, although poor quality, show the diverse range of parachute delivery methods evolved by Grokhovski.

- PI Grokhovski testing a Percale parachute.
- Delivery of a motorcycle and sidecar combination by bomber.

Are there any more photos of his 1930s-vintage Inflatoplane?

Thanks for the photo of Grokhovsky landing a parachute.
Can you point to any other photos or books on parachute development in the USSR?
Sorry, but I do not read cyrrilic alphabet.

 

[Cy-27]

For many years my "Go-To" sources were "The Bulletin of the Russian Aviation Research Group of Air-Britain" quarterly issues.

These were lost when water damaged in a flood some years ago.

I still have the index file for the bulletin, with references to Grokovski. This is attached. Some of these entries may just be a one page diagram or section, not necessarily a multi-page article.

The article mentioned earlier in Reply #24 "The Red Star Airborne Operations" by Vladimir Kotyelnikov [Avia Master magazine - August 2004] has a lengthy piece on his work, with many photographs. It will need translating though..

If you use the Google web page translator tool, the following Russian pages still exist about his work:

115 лет назад родился Павел Гроховский, создатель первых советских парашютов и разработчик оригинальных методик десантирования. Мы вспомнили также его броневик на воздушной подушке, самолет-таран "Кукарача", глиняную бомбу и другие фантастические идеи.

More Grokhovskii designations explained for your enjoyment... The guy was quite eclectic! (some of the material in this thread will likely be rearranged later between this and the Designations section...).



G-1A

This type is mentioned here in passing (no further details I'm afraid):
http://www.rusproject.org/node/1176



G-2 to G-8 (containers)

The G-2 was a 1931 cigar-shaped cardboard container with a 3.5-meter diameter parachute at one end, able to carry loads up to 30 kg — like six rifles and 5,000 rounds of ammunition, for instance. It was accepted into service under the designation PG-2k. An R-5 biplane could carry ten of these "cigars":
The G-3 was a soft "air bag" container that stacked three 76-mm artillery shells or three light DP machine guns or three boxes of machine-gun belts. It was discharged with the same parachute as the G-2. After state, the G-3 started production under the designation PDMM.


In 1932, the G-4 (soft bag) and G-5 (hard oval-shaped plywood container) were both designed for 150-160 kg of cargo. In the same year the G-6 (for 80 kg) and the G-7 (for bulky cargo) were introduced, as well the G-8 cardboard cylinder (for food).

G-9

Grokhovskii thought about how to improve the mobility of the troops on the ground. In October 1932 he supplied the Air Force with the G-9 system, which consisted of two "Harley-Davidson" motorcycles hung up on the bomb racks under the wings of an R-5 biplane.
Each bike was put in a special frame and was equipped with two parachutes (collectively weighed 656 kg). More here:
http://vk.com/wall188878539_67

The G-9 is also mentioned here, along with the GN-4:
http://www.airforce.ru/history/chronology/1934.htm




G-11

A Grokhovskii (?) G-11 is mentioned here:
http://www.rusproject.org/node/1176



G-31

The G-31 is also given as the G-3-1 here, though I don't know if it was a redesignation:
http://www.airforce.ru/history/chronology/1932.htm



G-55

Finally, The G-55 designation applied to a system consisting in dropping miles of telephone wiring in a container from an R-5 aircraft. The system was tested successfully in 1935 and later designated as PRK-5, PRK PRK-10-30:

GN°4 and GN°8

The GN°4 five-seat glider (apparently the same as GN-4) and GN°8 (a four-seat glider designed to be towed behind a fighter) are described here:
http://www.ljpoisk.ru/archive/3766292.html

It is also mentioned here (as the GN-4):

The glider "G-1 a" is a typo there was no such glider

The glider "G-1 a" is a typo there was no such glider

Thanks for the clarification!
