Sweden is generally a very small player on the helicopter market, however, there are a number of projects throughout history. If you know any little information, please post here. Below i put a Westland Lynx armed with eight RBS70 anti aircraft missiles, probably a mockup, iirc from 1989.

Tank have always got much better armor compared to any helicopters, they can also be equipped with active hard kill protection system that can destroy missiles physically. Tanks can hide much better because both their radar signature and infrared signature can blend better into the background...

From a book on Czech helicopter projects:

Hi, I found on Net,this stuff of helicopter-carsbut I suspected in them, so put them here ?.

Hi, the Hindustan LAH Light Attack Helicopter from Flightglobal. http://www.flightglobal.com/PDFArchive/View/1990/1990%20-%201243.html

Experimental helicopter built by Otto G. Luyties of Baltimore, in collaboration with Prof. Wood of Johns Hopkins. The goal was to prove the aerodynamic advantage of helicopters over conventional aircraft at the time, while competing for the Scientific American trophy for gasless machines.

Hi, also from the book, Romanian Aeronautical Constructions,the engineer Cristea Constantinescu designed the C.O.1,an autogyro-helicopter with a pusher air- screw and two co-axial rotors in 1934,he continued by C.O.2,a modern helicopter by its time,design began at 1938 but never completed.

I hope someone can give me the correct designation for this small co-axial rotor helicopter. It appeared around 1960-1962 in Germany. I have seen it described as the K.B. Kindermann Helicopter, but also as Rotocar 1 by Ing. Josef Wagner and his Wagner Helikopter Technik company.

From Flight, December 1958.

The German engineer Alois Riedly had filed a patent (N°709077) in 1937 for a helicopter using two pairs of intersecting rotors, the two pairs fitted with different rotor shaft angles. Riedl later worked for the Henschel Flugzeugwerke and maybe a project for a helicopter with intersecting rotors...

Hi, the CW Helicopter Research Co. was designed a high-speed three-seat all-metal light helicopter from Belgium, powered by one 245 hp Lycoming O-435 engine. Early the company created a series of projects,CW I,CW II, CW III,CW IV up to CW 8,no details about them. Later appeared the CW-105F...

I found this on the internet on a google search for attack helicopters--a strange bitmap illustration of an attack helicopter. I found no source, and it dissapeared of the internet the time I saved it. Strange :o! Has a few too many of supports above the wheels and the gun, I think.

Again, Uttley's "Westland and the British Helicopter Industry 1945-1960" is the source, where I found a helicopter project which is unknown to me. The General Electric jet-propelled helicopter has been designed in 1943 (unknown date of cancellation). Does anybody know something more on this...

Interesting counterpart of Boeing X-50 from Russia. Canard rotor wing helicopter shown in TV document "Udarnaja sila". No further info (yet).
