possibilities of using liquid propellant rockets for<br />
flights with low trajectories.<br />
After the 07 and 09 rocket projects, work on the<br />
05 rocket was begun. This rocket (Figure 8) was<br />
designed to use the nitric acid/kerosene ORM-50<br />
engine developed by GDL. Design of the rocket was<br />
completed in 1933 when the Rocket Research Institute<br />
was being organized, and RNII continued its<br />
further development.<br />
On the basis of the 05 rocket's design, RNII<br />
developed, under the sponsorship of the Ail-Union<br />
Aeronautic Research and Technical Society<br />
(Aviavnito) the stratospheric rocket "Aviavnito"<br />
(Figure 9). It used the 12-K liquid rocket engine<br />
which operated on liquid oxygen/96% alcohol<br />
and generated 300 kg thrust for a duration of<br />
60 sec. However, the flat stabilizing fins of the<br />
05 rocket were replaced with new, profiled hollow<br />
fins. The initial rocket weighed approximately<br />
100 kg, of which 32 kg was propellant. The 12-K<br />
motor developed a specific impulse of 205-207<br />
kg-sec/kg. The entire engine installation weighed<br />
15 kg. 4 The rocket was designed to reach an altitude<br />
of 10,800 m and contained a parachute. An altimeter,<br />
of the barograph type developed by S. A.<br />
Pivovarov, was mounted on the rocket.<br />
The initial launching of the Aviavnito rocket took<br />
place on 6 April 1936. Pravda published a article<br />
about the launching which included a photo of the<br />
rocket in the launching position prior to take-off.<br />
The correspondent described the rocket flight as<br />
follows:<br />
The engineer has switched on the electric ignition plug.<br />
Gray smoke of evaporating propellant. Spark. And suddenly<br />
a dazzling yellow flame appeared at the base of the rocket.<br />
The rocket moved slowly up the guide rods of the launching<br />
frame, slipped out of its steel embrace and rushed upwards.<br />

The (light was an extremely impressive and beautiful spectacle.<br />
A flame rushed out of the motor nozzle. The rapid<br />
flow of gas was accompanied by a low-pitched roaring sound.<br />
A parachute opened showing its white canopy after the<br />
rocket reached a low altitude and then landed smoothly on<br />
a snow field/'<br />
For subsequent launchings a wooden tower was<br />
constructed with a guide, 48 m long, constructed<br />
from a narrow-gauge rail, which engaged the<br />
launching lugs of the rocket.<br />
On 15 August 1937 an Aviavnito rocket reached<br />
an altitude of 3000 meters, 6 but on descent the<br />
parachute was torn from the rocket, and the rocket<br />
was severely damaged upon impact.<br />
Some of the individuals working on the second<br />
team were, F. L. Yakitis, V. S. Suyev, V. N. Galkovsky,<br />
S. I. Kruglova, O. K. Parovina, N. I. Shul'gina,<br />
V. A. Andreyev, E. I. Snegireva, and N. I. Yefremov.<br />
In summary, the results of the GIRD second<br />
team's activity were as follows:<br />
1. Bringing about the flights of early liquid propellant<br />
rockets.<br />
2. First use of liquid oxygen and other oxidants<br />
in combination with various fuels.<br />
3. The first rocket to use liquid oxygen and a<br />
semisolid (hybrid) fuel.<br />
4. Initiation of the development of a pump driven<br />
by liquid oxygen.<br />
5. Developing and experimentally proving methods<br />
of calculating rocket design and performance.<br />
All the above problems were studied experimentally<br />
and in most cases results were obtained which subsequently<br />
served as the basis for realistic tasks and<br />
development programs.<br />
The main task of GIRD and its second team was<br />
to prove that the principle of jet propulsion was<br />
quite workable even with the state of the art of
