Let me take liberty to recommend a book or two, even if the question was not directed to me, in case you want to stay in the comfort of your desk. :wink: Anderson's "Intro to Flight" is very a good book to start with. If you want to get past that for more rigor you can go to same author's...

Absolutely love the idea of acknowledging and celebrating the people behind the scenes who made this possible. A commendable effort by tarmak007. Loved reading the article. Great Job by the teams. In this occassion, we should also recall the contributions of Dr Srinath Kumar of NAL, Shyam Chetty's ...

This seems to be a fairly realistic and believable account of China's effort at an AShBM. <u r l> An article like this evokes empathy about the tech difficulties faced by China <snip> Shiv garu saw only tech difficulties. What about the language difficulties in the article? Even the poor language/t...

Don't know if it is appropriate for this thread, but the article title is interesting: "Long March: China’s fifth-generation fighter is years away "

Thanks so much ashokpachori. The article you pointed, proves that the blog quoted above was inaccurate.
However the worth of the total "Agni Sakshi" story should not be undervalued for such errors.
Cheers.

The Prithvi Point & Kalam : This is the spot where a Prithvi missile landed during its launch in 1992/1993 . (I am not sure about the correct year!) The missile was launched from Balasore, and, Kalam and team came in search of it, following its trajectory, only to land in this island (uninhibit...

Jeff Wickline

one quite noobish question....what exactly is the role of light jet fighters in wartime?? The same questions from me too. Could not get satisfactory answers from Wiki or Google. Most links point to Tejas only. But we would like to know what a "light" fighter/combat aircraft is expected to...

How is the water stopped from entering a sub through the propeller shaft opening in the hull? Cheers.... The problem of water ingress through propeller shaft is not unique to submarines. The same is (qualitatively) true for ships as well as in household water pumps. The major difference in submarin...

Is there a BRF thread which discusses strategic rarer earth?

One thing I wish to know is why Fiber-optics were selected? Was it because of the inherent resilience against a EMP attack or was it to keep the weight down. If EMP attack was the main criteria, then we are far away from creating a truly optical system, using only optical communications and optical...

Jeff Wickline

This episode is shorter than expected.

We need more!

Jeff Wickline

^^^^ Now that the real designers have taken interest, the newbies and not-so-experienced members should take back seats and watch and learn.
One more point, the "newbies and not-so-experienced" members may, however, congratulate themselves for keeping the thread alive.
Cheers and shalom.

Jeff Wickline

^^ When? Where?
Would like to be a non-player cheer leader (sans lungi dance, have arthritic tendencies).
Would some one please list out the components to be designed as an intro?
Would we go for the 40T version, suitable for the northern defence?

Jeff Wickline

Jeff.... Should we go for a internal bomb bay? If so, I have been checking most of the strike missiles and 2000lbs bombs should be able to fit inside a 5 m x 1 m bay. In fact 1 m width would mean most of the time 2 can be carried inside. Also, what should be the loiter requirement and range require...

Jeff Wickline

Really scary! More so, as Julio Fernando is a "Mod" of "Prahari" !

Jeff Wickline

Sir, What abhibhushan sir says here is that there would not be a significant presence of fighters for air defence and not about SAM threats... I envisage atleast a tunguska type mobile air cover for the enemy logistic and armor convoys. Presence of long range SAM's is slightly. JMO. Vignesh, in tha...

Jeff Wickline

Rahul Sir, ^^ This prompted me to comment that "specs are converging". We now have to sub-threads of solutions. Thread#1: Modify the Tejas into an attack version, as you have suggested in an earlier post. This requires serious deliberations. Thread#2: Nuby jingos like the undersigned and M...

Jeff Wickline

So am i... BTW.. what about resuming the design from the earlier posts in the thread based on the inputs from Abhibhushan sir... @ Bala, following your suggestions, I am summarizing the earlier inputs from Abhibhushan sir. The numbering in bold added. Retained only the requirement part. 1. I want t...

btw jeff and b_ambuj sir i sometime back posted a jet and bomber design...the specs were very basic....but i still think it has some quite good innovations.....the jet and bomber had a lot of commonality..... @Manish i was trying to locate your earlier post but could not . Can you please help me ou...

Jeff Wickline

what is the most common CAS platform type of our era ? attack helicopters ? all attack helos carry cannons except one model of the tiger, which too can fit external gunpods if needed. I don't suppose I've to mention the su-25 or the A-10. strafing continues to be very potent against all kinds of mi...

A few questions to the mentors: 1. Is the use of M/c guns for air to ground is still in vogue? Or is the role of gun is limited as a self defence against hostile aircraft. We thought A2G rockets are more in vogue. 2.With the prevalence of MANPADs like FIM-92 Stinger,Thales Starstreak, 9K38 Igla et a...

Jeff Wickline

Jeff sir, No matter what we do, whatever we come up here stays as an theoretical design, unless we flight test atleast a model aircraft.. any ideas on that??? Or should we be just design the bird on paper be satisfied like the babus that govern us.. Vignesh Sir, With our resources, for the time bei...

Jeff Wickline

^^ some suggested ground rules. 1. Mentors, from time to time may assume the role of Users. 2. Designers should not argue with "members at large", from the "conservation of energy principle". 3. Designers may seek clarifications from the users and mentors but not argue with them....

Jeff Wickline

^^ Very pertinent questions and difficult too, Shiv Saar. I think I can now (after the last post you have quoted) would be able to answer some of these. Unfortunately, I am on my way to airport and would not have net-access for three days. (Would you believe it, in 2010?). More importantly, I would ...

Jeff Wickline

^^ certainly you have visited the Wikipedia page of the same name. It has a good overview and many links. But these are about general aspects and not related to Indian Defense forces. AFAIK there so far DRDO has not reported any initiative. (Would search again this forum though .) It would be up to ...

Jeff Wickline

If we get enough participants with some free time, we can certainly start a new thread "designing our strategic bomber". It would be an interesting exercise with choice of airframe, engine etc. Have to be stealthy as well. It would not cost the nation much as "we" would be doing ...

Jeff Wickline

^^ Thanks B_Ambuj (the earlier post) for the criticisms. This kind of criticisms are necessary to debug our thoughts regarding "our" very own designed combat aircraft. Here, "we" stands for the mango jingo's and not ADA, nor IAF, nor HAL. So this thread can take some liberties re...

Re: Beriev A-40. Thanks for drawing our attention to the above. It is indeed a remarkable aircraft. The engines are also interesting. But it appears that the sea based operation is only possible at relatively calm condition (<2m wave height). While it may be OK for large lakes and black sea, it woul...

Single seat? Twin seat? Which engine? One engine or two? Why tailplane? Why not canards? Why not pure delta since we have experience? Why twin canted rudder-elevator? What is the need for supercruise as a design goal? Would supercruise be dispensable if range/payload goals are met? HF 24 could supe...

it can't be explained by someone in one post or even a dozen. there's a very approachable book aircraft design : a conceptual approach by daniel p raymer. you need 1st year engn/physics/maths background to get the basic idea. thank you sir....guess still have a year to get that book!!

Couldn't we use cruise missiles and ballistic missiles for the same tasks? A bomber would be very vulnerable IMHO. Just a thought.

Jeff Wickline

Thanks Saik saar,
an excellent link. I too got interested. It would be a good past time to convert these codes into matlab/scilab codes with interactive screens and graphic outputs.
Would report progress or otherwise.

Jeff Wickline

are there any softwares(free) for designing aircrafts??where can i get them?? I do not think any good freeware would exist but would keep on searching. I vaguely remember some toy-ish program, quite some time back. Incidentally, some textbooks have software for different aspects of aircraft design....

Jeff Wickline

Jeff, your specs for "Ground Attack" some what matches the requirements of "AMCA" only thing is that "AMCA" is specifically not a "Ground Attack" aircraft but its going to be a "Multirole" aircraft. Thanks for the comments. I am aware that AMCA woul...

Are you thinking of Tejas X 2 with stealth? Thanks for caring to respond to my post Pratyush sir. I did two things: 1) Took hint from the Mod's comment >> Forget even the 4++ part, what I basically want is a viable 4th gen jet, twin-engined and twin-seating, affordable and able to be made in India....
