Description
DARPA is soliciting innovative research proposals on the topic of a Submersible Aircraft. In particular, DARPA is interested in a feasibility study and experiments to prove out the possibility of making an aircraft that can maneuver underwater. The proposal needs to outline a conceptual design along with identifying the major technological limitations that need to be overcome in order to maneuver an aircraft underwater. In addition to the conceptual design studies, performers need to outline experiments or computational models that will be used to demonstrate that the major technological limitations can be overcome.
----------------
In development since 2008, DARPA's submarine aircraft has reached design proposal stage, and several outside developers have submitted designs. DARPA could start allocating funding to developers in as little as a year.
QUESTION of the WEEK
.
1) Identify the concept illustrated by the drawing above: what was its abbreviated name?
.
2) What was the approximate year of the concept and describe its weapons?
.
3) What country attempted to develope it and did it ever become viable for service?
.
4) Two major obstacles needed to be overcome before a submersible aircraft like the one illustrated could become viable; what were they?
.
5) DARPA's concept will be unmanned, like this, (a fact journalists omit); have the 2 major design obstacles (see question 4) been overcome?
.
ANSWERS: 5) - pending until further notice; 1)-4) - SXAXTXUXRXDXAXY MONDAY

1) Concept by young Russian cadet named Ushakov. Abbreviated name "LPL", russian for Flying Submarine.

2)Year of concept 1934. Two 18" Torpedoes.

3) Russia attempted the concept but it never became viable and project was abandoned.

4) Not enough clearence from propellers to water, and very limited range of op's, 500 miles. Weight main drawback.

5) Couldn't locate info regarding this Q.

OK Cookie, where did you find that? I found conflicting stuff and had a hard time deciphering which concept belonged to what facts... Gahh, I am thankful this wasn't a graded assignment :)

Just did a lot of Googling mate, and yes, I found conflicting info as well, so I'm not sure exactly what is true and was isn't.
