YF-4E PACT / CCV Demonstrator

Hi,

Comparison of vortex lattice predicted forces with wind tunnel experiments for the F-4E(CCV) airplane with a closely coupled canard - NASA Technical Reports Server (NTRS)

The F-4E (CCV) wind tunnel model with closely coupled canard control surfaces was analyzed by means of a version of a vortex lattice program that included the effects of nonlinear leading edge or side edge vortex lift on as many as four individual planforms. The results were compared with...

Hi,

hesham,

Now that the NASA archives are down for who knows how long, would it be possible to have you email me a copy of this report? I am doing research on the F-4 and would like to look at it. If you respond, I will send my email address.

Yf-4e demonstrator with uprated engines and canard. Anyone have more
info on this project? Was it fly by wire? There were claims it had f-15 like performance and could turn inside an f-16.

Perhaps you should search for the report linked by hesham in this thread
http://www.secretprojects.co.uk/forum/index.php/topic,5597.msg192938.html#msg192938
Not directly available anymore, but maybe someone still has it.

Thanks Jemiba...haven't found too much about this so far.

Hesham's link is working again. I also found this:

https://www.sto.nato.int/publications/AGARD/AGARD-CP-157/AGARD-CP-157.pdf

The paper comprising chapter 12, starting on page 143 of the conference report, discusses the the SFCS (Survivable flight control system) and PACT flight programs. The PACT program is discussed on pages 155-166 of the pdf and includes performance gains from FBW, reduced stability, slats, and canards.

Just eyeballing the turning performance graph, it looks pretty similar to a graph I remember from one of the early F-15 books comparing the difference between the F-15 and the F-4.

Welcome aboard Apparition13,

and many thanks.

F-4 #12200 has been a favorite aircraft of mine for some time. Here is a link to Ron Downey's Aviation Archives article on this bird.

YF-4E 62-12200 Fly by Wire

One of the most interesting aircraft around during my working days was 62-12200. Among other things, it was the aircraft for the Fly-By-...

What is the difference between the three programs of CCV, PACT and SFCS?
I'm a bit confused.

I refreshed the link in the first post with the current URL.

SFCS (Survivable Flight Control System) - A digital Fly-by-wire adaption of YF-4E prototype.
PACT (Precision Aircraft Control Technology) / CCV (Control Configured Vehicle) - Adaption of YF-4E from SFCS with canards to test CCV.

Here's an article which gives a good overview of the entire AFFDL program on Active Control Technology.

AFFDL EXPERIENCE IN ACTIVE CONTROL TECHNOLOGY
by Robert P. Johannes and Robert A. Whitmoyer Air Force Flight Dynamics Laboratory



SUMMARY
This paper traces the evolution of active control technology (ACT) from the viewpoint of the Air Force Flight Dynamics Laboratory (AFFDL). Emphasis is placed on the aero- dynamic control forces necessary to fully exploit ACT and in describing AFFDL development programs which merge these two disciplines and transition technology into operational flight equipment. Specific ACT programs described are: (1) the LAMS Program, (2) the CCV B-52 Program, (3) the SFCS F-4 Program, (4) the CCV/PACT F-4 Programs, (5) the Vari- able Stability NT-33 Program, (6) the CCV YF-16 Program, (7) the A-7D Digital Multimode Program, (8) the IFFC I/FIREFLY III Program, and (9) the AFTI-16 Program. Experiences indicating areas of need for extension of fluid dynamics technology are also discussed.
